Why might you want to use the Commutative Property to change the order of the integers in the following sum before adding?
-65+ (-189) + (-35)

You might want to use the commutative property because adding all three together in your head is more difficult than -189+(-65)+(-35), as you can quickly add up -65 and -35 upon seeing they equal -100, a nice number, so then its easier to add -189+(-100), which equals -289. Piece of cake. :)

Step-by-step explanation:

a² + b²= c²

24² + 7² = c²

c= 25

- 70

this is the answer for you hope it
