Why Algebra?

Posted in Education Special, Life Of Science, Mathematicians Tips on February 14th, 2010

After an exhaustive research over the reasons behind the maximum school dropouts, a consistency was found in the answers of the majority of the participants pointing towards Algebra. It is well said, that just the knowledge of the tutor is not alone sufficient to build interest in the subject for the pupils. It’s the technique; the subject matter is delivered to its recipient which contributes a lot for developing interest in the disciplines.

What is Algebra?

In short, algebra is a subdivision of maths that deal with letters in place of numbers in order to work out equations; therefore, algebraic equations can be viewed as a scale. Algebra includes real numbers, complex numbers, matrices and vectors.

The Different Spheres

Generally, algebra spreads across many domains of mathematics. for example; Multiplying exponents, dividing exponents, Solving quadratic equations , Finding Greatest common factor or GCM, Multiplying, Adding, Subtracting fractions and many more.

If these areas have shocked you, then I must give you some definitions which will really relieve the gravity and give you the real effect of algebra.

Exponents are just shorthand for denoting multiplication of identical factors. Fractions on the other hand are used for expressing numbers that are parts of a whole. Many such similar areas in algebra may sound dreading at first, but once you understand the simple concept behind it, you will be enthralled by its purpose. To put down a few more items - Mixed numbers, Quadratic formula, Graphing linear inequalities, solving compound in equalities , Factoring binomials, and Factoring polynomials; are all algebraic expressions.

Although you may find it confusing to comprehend mixed numbers, but it will really interest you to note that they are none other than a type of fractions. Similarly, graphing linear equalities may be self explanatory and there are many other similar algebraic expressions that may sound complex but are extremely interesting to work with.

How to Find a Tutor

If you want to quench your thirst for algebraic knowledge further and you do not have any teachers there is nothing to worry about. Because There are online lessons too. These lessons stress the practicalities rather than the technicalities, demonstrating dependable techniques. The algebra solver software programs can guide you step by step in resolving your mathematics sums and it can also provide explanations of all steps.

Do You Hate Algebra?

Algebra as a Scientific Discipline

Algebra science is the branch of mathematics that is interested in the study of structure, relation, and quantity. Algebra encompasses working with numbers, variables, sets of elements and also vectors as in linear algebra. You can believe algebra as one of the grandest branches of mathematics, if not the profoundest. Algebra includes categories such as Linear algebra, Universal algebra and Algebraic geometry.

Require Assistance in Studying Algebra?

Many software applications have come to the market in hope of helping students to develop the ability at solving algebraic problems . These software applications cover nearly all algebra modules such as solving and graphing different cases of radical equations, formulas and fractional inequalities. Such equations like quadratic, simultaneous, exponential, radical and linear equations will be simply, quickly and efficiently solved using these software applications. These software applications most probably will contain an algebraic object lesson and a wizard too; Moreover, algebra calculating systems facilitate a lot of algebraic operations for students interested in mathematics.

The Big Picture on Algebra

many students constantly wonder why we learn algebra; they can see no good reason behind it. Well, if we were to talk about algebra benefits, then it has both direct and indirect benefits, which I think, algebra students should be taught. The indirect benefit of studying algebra could be abstracted in working the learning ability in an organized design. As for the direct benefit, algebra has a bunch of uses in different sciences and industries.

Actually, algebra applications cover a lot of real life aspects such as in financial markets etc, for example in information technology development or business forecasts. Also, in various science researches like physics, quantum mechanics, Informatics and even in the military; in this article we shall explore how algebraic knowledge is applied in to IT.

Algebra in Programming

Relational algebra concepts were the basis for the relational database concept. Also, easy algebra was used in constructing of complex XML models and making XML database management systems. Furthermore, programming languages have been developed for solving algebraic expressions and formulas, like RPL which stands for ROM-based Procedural Language or ALF-Algebraic Logic Functional programming language. Some other advanced programming languages developed for the role of solving algebraic problems as AML-Algebraic Modeling Language, where this language describes the complicated problem, like compound optimization problems, then calls distinct external algorithms to solve the problem.

Is Algebra Really Important?

Posted in Education Special, Life Of Science, Mathematicians Tips on July 7th, 2009

An comprehensive research carried out to figure out the causes behind school dropouts shows that many pupils look at algebra as the culprit. It is well said, that just the knowledge of the tutor is not alone adequate to spring up interest in the subject matter for the students. It’s the technique; the subject area is explained to its recipient which leads a lot for developing interest in the discipline matters.

What is it?

A concise introduction of Algebra would be a arm of mathematics which substitutes letters for numbers; algebraic equation is a scale. The primary concepts of algebra includes real numbers, complex numbers, matrices and vectors.

The Different Arenas

Algebra in general spreads over a lot of areas. some such areas are Multiplying exponents, dividing exponents, Solving linear inequalities , Finding Greatest common factor or GCM, Multiplying, Adding, Subtracting fractions and many more.

If the above mentioned areas are already putting butterflies in your stomach, I hope that the definitions to follow will ease your anxiousness and give real perception in to the field of study.

Exponents is a notion that indicates multiplication of identical factors. Fractions on the other hand are used for showing numbers that are parts of a whole. Many such similar areas in algebra may sound dreading at the beginning, but once you understand the simple concept behind it, you will be captured by its purpose. To state a few more - Mixed numbers, Quadratic formula, Graphing linear inequalities , solving compound in equalities , Factoring binomials, and Factoring polynomials; are all algebraic expressions.

Although you may find it confounding to understand mixed numbers, but it will really interest you to note that they are none other than a form of fractions. Similarly, graphing linear equalities may be self explanatory and there are many other similar algebraic expressions that may sound complicated but are extremely interesting to work with.

How to Find a Tutor

If you want to quench your thirst for algebraic knowledge further and you do not have any instructors there is nothing to worry about. Because There are online lessons too. These lessons stress the practical ways rather than the technicalities, showing dependable techniques. Algebraic helper packages can assist you in the step-by-step process of understanding and working through mathematics sums in a systematic, stepwise way while offering examples and explanations for all steps involved.

Screening and Indicators Provide Clues into Diagnosis of Mesothelioma

Posted in Health Info, Life Of Science on June 21st, 2009

Cancer of the mesothelium has a few primary symptoms. The primary symptom of pleural mesothelioma is a lack of breath caused by pleural effusion ” the buildup of fluid in the pleura, or membrane, surrounding the lung. Another common symptomis chest pain because the tumor is attacking the chest wall. Symptoms may also include fatigue, loss of weight and night sweats

The main indicatorof patients with abdomen mesothelioma, which begins in the abdomen, is the swelling of the abdomen because of fluid accumulation (ascites), bowel obstruction, and stomach pain.

It is key to understand that other afflictions or diseases could be causing these symptoms. Nevertheless, you should see a doctor if you have been exposed to asbestos and have experienced any of these symptoms.

Mesothelioma is hard to identify, because less serious conditions also cause similar symptoms. Typical symptoms:

  • Difficulty breathing
  • Chest or lower back pain associated with an excess of fluid in the pleura
  • Burning up
  • Upset stomach
  • Hoarseness
  • Having trouble swallowing
  • Coughing up blood

Self-diagnosis should never be attempted. Sufferers of the above symptoms should not panic, and should consult their doctor. Performing a biopsy is the standard way to confirm the condition. A pathologist takes a small tissue sample from the suspected region and examines it to return a highly accurate diagnosis. Biopsies are typically pain-free.

CT scans (Computed Tomography) are an option to avoid a biopsy. This is an X-ray procedure where a scanner is moved around the body to snap cross-sectional pictures. Sometimes, the patient ingests a dye that helps define the picture. CT scans have an advantage over biopsies by being easier and non-invasive, and they are considered an effective way of diagnosing the disease. Opinions vary whether a CT scan or biopsy is cheaper. If there are abnormalities, a biopsy may be needed on top of the CT scan to confirm whether or not the irregularity is a tumor, and if so, whether it is malignant or benign. Diagnosis of pleural mesothelioma is also possible by looking for cancer cells in a sample of fluid from the pleura.

Mesothelioma can also be screened and then diagnosed by any of these methods. Patients are screened when they suspect they may be at risk but do not have typical symptoms, to catch the cancer early or to make sure the patient is not otherwise in danger. People who need to be screened include those with a history of asbestos exposure..

Algebra - the Math Foundation

Posted in Education Special, Life Of Science, Mathematicians Tips on April 15th, 2009

Algebra is one of the most crucial subdivisions of maths that is often introduced to students in Jr. High. As a matter of fact, many pupils find algebra as a hard subject area to understand. Algebra is one of the complex arms of mathematics that takes the student through a study of structure, relation and quantity.

The Common Methods

Although ‘variables’ is one of the often used terms in computer science, this is first presented in algebra. This is frequently used when adding and subtracting radicals . When adding or subtracting radicals the radicals essentially be the same order before you add or subtract them.

You can take the frustration out of getting the least common denominator by listing the multiples of each denominator and dividing by 2,3,4, and so on. After that you should look at the smallest number. An example is multiples of 5 are 10, 15, 20, 30. Multiples of 6 are 12, 18, 24, 30, and multiples of 15 are 30, 45, 60. As you can see 30 is the smallest number that appears in the multiples list.
If you are supposed to simplify a fraction, it can be done easily by finding a common factor in the numerator and denominator. A common factor is going to be a number that will equally divide into both numbers. As an example 3 is a common factor for 6 and 12. Three will evenly divide into 6 and into 12. Two being a common factor for 4 and 14 is another example for this. You will repeat this same process until there are no common factors left. This can also be done by finding the greatest common factor of both the numerator and the denominator. You will divide the numerator and the denominator by the greatest common factor instead of the common factor.

Getting out of Trouble with Algebra

Sometime you might find troubles getting along with algebra and can’t seem to find the answer you need. In this case, an algebra problem solver, typically a software, will be an ideal resolution for getting aid. With one of these computer package you can simply input the figures related to the question and your problem will be solved immediately. Having access to an algebra problem solver can mean the difference in passing or failing. Most pupils cannot afford a tutor and they might not be available when you need them at times. With an algebra software you will have access to the solutions you need, anytime you need them.

Two Hearts Are Now One

Posted in Life Of Science on April 5th, 2008

It is fitting that I should write this story on Valentines Day, for this is a story of two broken hearts; healed and mended, then melted together as one–in an instant. This is a story of True Love.

Anyone who comes from a broken family understands the pain of divorce. I was twenty-seven years old when my parents divorced, and while some people think that a person shouldn’t be “affected” by such things once they are adults, I can assure you–I WAS! I was shocked when my parents divorced. I had no forewarning in the natural. But, on the day that my dad told my mom that he was moving out, I felt a great anxiety in my spirit–so great that I told my husband, “Something is terribly wrong in California. I want to phone home.” Considering the fact that I was three thousand miles away, on a remote island in Northern Canada, when I felt this anxiety, you can appreciate that I was deeply affected.


Pain and confusion became constant companions as I tried to “understand” what had happened–what right did he have to leave my mother? Whose standard was he using to exercise his right to leave her? What had she done that was so terrible that he could not live with her? I had questions and I asked them of nearly everyone around me. I asked God the same questions, and in so doing, I realized that my own life was in quite a mess. As I came into a better alignment with God, I searched the Bible for “the answer” to all my questions about my dad. Since he had been a Baptist minister at one time, I felt certain that he would know and obey what the Bible said about such an important issue.


About two years after the divorce, the whole family gathered in California–for one of those BIG attempts to bring reconciliation–I felt certain that dad would listen to God’s Word. I reached for my Bible and said, “Dad, look at what God has to say about what you are doing.” Before I could find the carefully selected passage of scripture that would straighten this mess out, he stood up and loudly cursed me, the Bible and the whole family. Then he walked out. Needless to say we were all in shock. The shock of that cursing lasted a long time–eighteen years for myself, and twenty years for my brother and sister.


Eighteen years is a long time. Think about it. It generally takes eighteen years to graduate from high school. A whole “lifetime” of events takes place in eighteen years. During those years, contact with my dad was minimal. A card from him on my birthday, Christmas cards, the odd phone call which always stirred up the pain. Someone would hear about something that he was doing and he would again become the topic of our conversation for weeks. My mother never stopped talking about him. She never let him go.


My mom maintained her relationship with God throughout this long painful separation. She read her Bible, went to church, cared about us kids and loved her grandkids. She worked as a secretary and saved her money so she wouldn’t be a burden on anyone when she retired. But, always, she was obsessed with talking about my dad.


I would say that most of our conversations about him were judgemental. After all, we read our Bibles; we knew that what he had done was wrong. She had done nothing that the Bible sanctioned as reason for divorce. By the time of his third marriage, we knew he wasn’t coming back to her. Still, his actions and their effect on our lives were frequent topics of our conversations.


After many years, I gave up hope for my dad to ever be reconciled to his family. I doubted he was even a Christian. I felt he was a totally lost, immoral, unstable, unsavory person. That was a very dark time for me. Gradually, I got used to the darkness in my own soul–it seemed normal.


Mother did retire and she moved from California to Canada to be near my family. She had missed out on much of the growing up of my five children, and she wanted to get to know them. She bought a condominium two blocks from my house and the kids enjoyed having “Gran” live so close. One year after moving here, she was diagnosed with Lou Gehrig’s disease.


Lou Gehrig’s disease was a death sentence. There was no cure. There was no treatment. I spent four months pryaing and asking God to heal my mother. Finally, the answer came: “Help her die.” I accepted her diagnosis and did all I could to help her.


I wish I could tell you that I was a “good little Christian” who praised and thanked God every day for His righteous judgements–but, the truth is that I questioned God. I really felt that it was unfair of Him to let my dad go free, when he was the one who had done this great wrong to his family, and to allow my mother to die this cruel death. Finally, I asked God, “How do You see this situation?” The answer He spoke to my heart would one day transform all our lives.


About a year after my mother died, I felt something stirring inside of me–a desire to see my dad. In the long eighteen years of separation, I had only invited him once to visit my home and during that visit I had tried again–and unsuccessfully, again–to confront him with the Bible. I had no reason to expect that another visit would end differently, but I honored that desire anyway and invited him for a long weekend.


My dad came armed with his own arsenal of justifications. He knew what to expect from me. I hadn’t planned anything specific to confront him on–I didn’t need to, I had a whole list of offenses that I could whip out at any given moment. So, the weekend progressed–awkwardly, but quietly.


I had no idea that Spirit was about to move in on us in a powerful way. I simply invited two gentlemen friends over for lunch. They lead a prayer group I attended and I suppose I hoped they would “say something” important to my dad. If not, it was a way to let others meet my dad and see the man who had so wounded me. We were sitting around my dining room table, when one gentleman began telling the story of a young soldier in Napoleon’s army who had gone A.W.O.L., been caught and was now about to face the firing squad. This young man’s mother came to Napoleon and pleaded for mercy for her son. Napoleon replied, “He doesn’t deserve mercy.” To which the mother implored, “But, Sir, if he deserved it, it wouldn’t be mercy!” At that, Napoleon allowed the boy to live. After telling this story, the gentleman said, “I have no idea why I told that story. It just came into my head.”


As he has been speaking, I felt the strangest sensation of heat come over my head and into my chest. Without wavering, I said, “I know why you told that story.” I turned toward my dad and gently said, “Dad, when mom was dying, I felt that God was being very unfair. So I asked Him what He had to say about the situation. Would you like to hear what God had to say about you and mom?” The room was very quiet. I could tell that my dad was afraid to know. But, after a few moments he indicated that he would.


I felt the heat increasing as I reached deep into my soul for those words, “He said, ‘I could not heal your mother, because she would not forgive. But I see the wounds upon your father’s heart, and I have pity on him.’” In the moment I spoke those words, the power of Spirit hit both of us “like lightening.” We stood up, pushed our chairs back from the table and fell into each others arms, sobbing. After quite a while of crying and kissing, we sat down again–even the two gentlemen present were crying–and I realized that I could not remember even one of those offenses on my “list.” The whole list was erased from my memory–and five years later, it is still gone!


From that day on, my dad and I have had a relationship that is far beyond mere “reconciliation” or “recovery.” We never had a relationship like this before–ever! This is a totally new relationship! We talk on the phone every weekend, we plan visits around special holidays, we go to conferences together. Where before my dad had been closed to the “things of the Spirit,” due to the wounding caused by my own judgementalism and legalism, now he is hungry for more of the Spirit. Right away my dad began having powerful dreams which he KNEW were from God. He shares these dreams with me and we discuss their possible meanings.


Two years after this momentous day, my dad was reconciled to my brother and sister. My family traveled to California where we had a true “family reunion.” It had been twenty years since the divorce.


Whenever my dad and I are together, we look for an opportunity to share our story. It is a story that brings hope to hopelessly broken relationships. It is a True Love story.
