Why might you want to use the commutative property to change the order of the integers in the following sum before adding

Commutative Property of basic numbers is a property in which you can move around or move the order of the numbers yet still get the same sum or product. This property only applies to the addition and multiplication operations. In which why you might want to consider the commutative property? Well, first thing is that you get the idea that for example, 1 + 2 + 3 = 6 that if you change the order or move around the numbers like 3 + 2 + 1 = 6, you still got the sum. And next is because if will be help for more complex equations like combined operations in a single equation.  1 + 3 – 4 x 6 / 2 = 8 ; 3 + 1 – 6 x 4 / 2 = 8
