Algebra is a part of mathematics (maths) that helps show the general links between numbers and math operations (adding, subtracting, multiplying or dividing) used on the numbers. Algebra does this by using letters ("a","b","c"...) or other symbols to represent numbers, either because the numbers are unknown or because the numbers change during the course of the problem, in which case the letters are called variables. In many math problems, time is a variable, often represented by the letter "t". Using the basic ideas in algebra can help reduce a math problem to its simplest form making it easier to solve difficult problems. Algebra is taught in school to help in harder mathematics, science, and engineering classes.
Here is a simple example of an algebra problem.
Sue has 12 jellybeans, Ann has 24 jellybeans. They decide to share, so that they have same jellybeans. Let "x" represent the number of jellybeans Ann gives to Sue. Then we want 12 + "x" = 24 - "x".
Here are steps you can use to solve the problem.
1) Subtract 12 from both sides of the equation. This gives "x" = 12 - "x".
2) Add "x" to both sides of the equation. This gives 2"x" = 12.
3) Divide both sides of the equation by 2. This gives "x" = 6. If Ann gives Sue 6 jellybeans, they will have the same number of jellybeans.
Of course, this problem could be solved without algebra. The purpose of simple story problems such as this one is to teach algebra, so that the students can use algebra when faced with a problem that i
