Answer 2

-80

Explanation:

Use properties of addition to evaluate the expression.

`(-64) + ((-36) +20)`

Remove the parenthesis and simplify the number

positive times negative is negative

`-64-36+20`

Now simplify the expression

When the signs are same then we add the numbers and put the same sign

-64 and -36 becomes -100

`-64-36+20`

`-100+20`

-80
