What property of real numbers is 3+((-5)+6=(3+(-5))+6

The associative property

Step-by-step explanation:

I assume you meant 3 + ((-5) + 6) = (3 + (-5)) + 6.

This is the associative property of addition which states:

a + (b + c) = (a + b) + c

This property also works with multiplication.

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72
