Question

Explain why the commutative of addition rule will work when subtracting integers but they don't work when subtracting whole numbers. Give examples to provide evidence for your reasoning.

Answer 1

Simple example of why subtraction is not commutative


10 - 7 = 3

but

7 - 10 = -3


so 10 - 7 does NOT equal 7 - 10


So in general,


x - y does NOT equal y - x

you look like a young john travolta

Answer 3

commutative of addition does not work with subtraction of integers , huh>
