What property is 4x3 3x4?
Commutative property of multiplication: Changing the order of factors does not change the product. For example, 4 × 3 = 3 × 4 4 \\times 3 = 3 \\times 4 4?=3?, times, 3, equals, 3, times, 4.What is an example of associative property?
Associative property of addition: Changing the grouping of addends does not change the sum. For example, ( 2 + 3 ) + 4 = 2 + ( 3 + 4 ) (2 + 3) + 4 = 2 + (3 + 4) (2+3)+4=2+(3+4)left parenthesis, 2, plus, 3, right parenthesis, plus, 4, equals, 2, plus, left parenthesis, 3, plus, 4, right parenthesis.- The associative property of addition states that the grouping of numbers does not change their sum. For example, (75 + 81) + 34 = 156 + 34 = 190; and 75 + (81 + 34) = 75 + 115 = 190. The sum of both the sides is 190.
