SOL A.1
VOCABULARY
A power has two parts, a base and an exponent.
The exponent tells you how many times to use the base as a factor. You read the power 23 as “two to the third power” or “two cubed”. You read 52 as “five to the second power” or “five squared.”
You simplify a numerical expression when you replace it with its single numerical value. Example: the simplest form of 2 ∙ 8 is 16.
You evaluate an algebraic expression by replacing each variable with a given number. Then simplify the expression using the order of operations.
