Answer:

-80

Explanation:

Firstly deal with the bracket

;((-36) + 20) = 20 - 36

; which then gives us... -16

Then in place of the bracket...replace it with the (-16) value,

; -64 + (-16)

; -80

Answer:

-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
