Base: the number that is multiplied Power: the number that is expressed as the exponent Exponent: tell how many times the base is used as a factor Standard Form: doesn’t not contain decimals Order of Operations: Step 1: Simplify the expressions inside grouping symbols. Start with the innermost group symbols Step 2: Evaluate all powers Step 3: Do all multiplications or divisions in order from left to right Step 4: Do all additions of subtractions in order from left to right

 Write each expression using exponents.  5 ⋅ 5 ⋅ 5 ⋅ 5 (-2)(-2)(-2)  (m – 7)(m – 7)(m – 7)(m – 7)(m – 7)  9 ⋅ x ⋅ x ⋅ x ⋅ y ⋅ y ⋅ y ⋅ y

 Evaluate each expression.  3 4 30 – a 3 if a = 2  –2(x + 2y) 2 if x = -4 and y = 3
