3×(800+10+9)=2,400+30+27=2,457
(5 x 6) + (2 x 6) = 7 x 6 = 42
0.4*(7.5 + 40) = 19
3 x 7 = 3 x (5 + 2) And since multiplication is distributive over addition, 3 x (5 + 2) = 3 x 5 + 3 x 2
It shows the Commutative property.
There's the commutative property of addition, which allows you to switch numbers around in an addition problem. 8+9 = 9+8 or a+b+c = c+a+b The associative property of addition allows you to move parentheses about. (a+b)+c = a+(b+c) The identity property of addition shows the following: a+0=a Dx1=D The inverse property of addition shows this: 5 + (-5) = 0
commutative property
3+8 = 8+3 is NOT an associative property but a commutative property. Associative property shows change of grouping while commutative property shows change of order.
