Associative Property of Addition

• multiplying three numbers, regardless of the way the numbers are grouped, the end result will always be the same. Example (a•b)• c = a (b•c)
• any mathematical statement which consists of numbers, variables and an arithmetic operation between them.
• the grouping of numbers does not change the sum. For example, 8 + (2 + 3) = (8 + 2) + 3 = 13

• the number of times a number needs to be multiplied by itself
