1-2 Order of Operations and Evaluating Expressions

Power: has two parts, a base and an exponent

Exponent: tells you how many times to use the base as a factor

Simplify: when you replace the numerical expression with its single numerical value

Base Exponent

Problem 2: Simplifying Numerical Expressions

ORDER OF OPERATIONSP: ParenthesesE: ExponentsM: MultiplicationD: DivisionA: AdditionS: Subtraction

From left to right. So if division comes 1st you will divide 1st and

if multiplication comes 1st multiply 1st

From left to right. So if subtraction comes 1st you will

subtract 1st and if addition comes 1st add 1st
