Square x (x^2)

Simplicity is often something not attributed to math, but squaring numbers should be. Do you know why we say “the square of x is…”? It’s very simple, we are really saying “the area of a square with sides x is…”. Remember that any rectangle has an area of its length times its height (area=(length)*(height)). And…

Keeping Track of Minus Signs in Parentheses: Subtraction

When evaluating an expression, the operations inside parentheses must be performed first. So 3 - (4-2) is the same as 3 - 2. Both are equal to 1. The correct treatment of plus and minus signs often causes confusion, especially when there are variables in the expression.

Solving an equation in one variable

In general, a one-variable equation such as ax+b=c can be solved by “undoing” the order of operations (PEMDAS). The order of operations is: parenthesis, exponents, multiplication, division, addition, subtraction. By doing the order of operations in reverse, we unravel the equation and isolate the variable.

Algebra 1: Sample Problem 1

A simple word problem using variables

Solving Equations

This tutor describes how to solve basic algebraic equations.

Algebra 1: Sample Problem 2

A similar problem to the first one, but with different known values. A key concept in algebra is using explicit information to determine implicit information, and solving for the unknown from there.
