Q:

Why is algebra important?

A:

Algebra is a method of solving mathematical equations in a way that allows a person to derive unknown quantities, such as bank interest, percentages or proportions. The use of letter variables in algebra to represent unknown quantities coupled with the ability to rewrite equations makes it easier to find the data necessary for a given situation.

Algebra is arguably the most basic of the higher mathematics disciplines. Without the fundamentals taught in algebra, it is virtually impossible to deal with geometry, trigonometry or statistics. These are all branches of math that everyone uses at some point without realizing it, as is algebra itself. For example, the interest equation "I = prt" tells how much interest a bank account has after a given time. To find the principal, or the amount initially in the account if other quantities are known, both sides of the equation are divided by rate times time, canceling it out on the right side in order to isolate P and solve the equation normally.

Linear algebra, involving graphs, help users to collect and analyze data. When presented with points of data, if a user understand linear algebra, he can plot them on a graph to create an equation in a computer system.
