Solution
Numbers written using exponents that represent repeated multiplication.
Powers
To find value of an expression by replacing the variables with numerals.
Solution
A mathematical sentence that contains the equal sign.
Equation
The distance a number is from zero on the number line.
Absolute Value
Pairs of operations that undo each other.
Inverse Operations
If you multiply each side of an equation by the same number, the two sides remain equal.
