Associative
Property
addition
(7+2)+5=7+(2+5)
9
+5=7+ 7
14 =14
or
multiplication
(7x2) x5= 7x(2x5)
14 x5=
7x 10
70=70
When we are adding or multiplying more than two numbers the grouping does not affect the sum or product
You can change the grouping of the
factors and get the same product using the associative property.
