Exponents are a way to express repeated multiplication. To evaluate an expression with an exponent, multiply the base number the number of times indicated by the exponent. For example, to evaluate 4^3, you would multiply 4 by itself three times, which equals 64.

Exponents: A number that indicates how many times a number is multiplied by itself. For example, the expression 'x^2' means that x is multiplied by itself twice. Order of Operations: The order in which operations must be done when evaluating an expression. Exponents must be done before addition and subtraction. Evaluating Expressions: The process of calculating the value of an expression using the values of the variables and the order of operations.

Exponents are used to represent repeated multiplication. For example, 2^3 is equal to 2 x 2 x 2, or 8. The '^' symbol is used to represent an exponent. It is also sometimes referred to as the 'caret' symbol. The base number in an exponent can have a negative value. For example, (-2)^3 is equal to (-2) x (-2) x (-2), or -8.
