Algebra is the branch of mathematics concerning the study of the rules of operations and relations, and the constructions and concepts arising from them, including terms, polynomials, equations and algebraic structures. Together with geometry, analysis, topology, combinatorics, and number theory, algebra is one of the main branches of pure mathematics.
As the main branches of pure mathematics, i think it is become the most important subject to understand. But, it is not an easy to make it. Need more effort to get it. I means it is need an advice for someone who know more about Algebra, it can be from parents or someone else.
But if we as a parents who doesn't know more about Algebra, we can use tutoring company to help our children to understanding this subject. For example, TutorVista. TutorVista is the leading online tutoring company in the world who provide 24X7 online tutoring. They are also provide free demo for first time user where they can try the service for free.
They provide online tutoring about Algebra 1 and Algebra 2. TutorVista's online Algebra 1 helps students of Grade 8, 9 and 10 with problems in topics on Algebra 1 like Exponents, Linear Equations, ratios, Real and complex numbers, quadratic formulae, Radicals, Polynomials, functions and more.
They will help to solve Algebra 1 problems with very easy and quickly. Here is the example,
In three more years, Jack's grandmother will be six times as old as Jack was last year. If Jack's present age is added to his grandmother's present age, the total is 68. How old is each one now?and for Algebra 1 Answers is:
Let 'g' be Jack's grandmother's current ageThere is just a little bit of example about TutorVista service. You can see more in their homepage, and of course it will be help your children to know about Algebra. And i think if your children understand about this lesson, they will be like it.
Let 'j' be Jack's grandmother's current age
If Jack's present age is added to his grandmother's present age, the total is 68
j + g = 68
In six more years, Jack's grandmother will be six times as old as Jack was last year
(g+3) = 6 (j1)
If Jack's present age is added to his grandmother's present age, the total is 68
j+g=68
Solving both equations we get Jack's age (j) as 11 and Jack's grandmother's age (g) as 57
