powers of 10 numbers like 10, 100, and 1,000, because they can be written with exponents
rounding finding the approximate value of a specific number or place value
example of Identity Property of Multiplication 46 x 1 = 46
example of Associative Property of Multiplication (9 x 4) x 5 = 9 x (4 x 5) = 36 x 5 = 9 x 20 = 180
