Answer:

-20

Explanation:

36 ÷ [-3] + [-4] × 3 − [-4]

In order to calculate this expression, all we have to do is following the order of operations:

Since division and multiplication comes before addition and subtraction

Then

36 ÷ [-3] + [-4] × 3 − [-4]

= (36 ÷ [-3]) + ([-4] × 3) − [-4]

= (-12) + (-12) − [-4]

= ((-12) + (-12)) − [-4]

= (-12 − 12) − [-4] (Recall : + (-a) = - a )

= - (12 + 12) − [-4]

= - (24) − [-4]

= - (24) + 4 (Recall : - (-a) = a )

= - (24 - 4) (Recall : -a + b = - (a - b) )

= - (20)

= -20
