## Keeping Track of Minus Signs in Parentheses: Subtraction

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

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 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.
