What does -3 -2x4 equals?

The rule in /mathemtics, when no brackets are given, is DO THE MULTIPLCATUION/DIVISION before addition /subtraction.

You calculator is programmed this way.

Hence

-3 -2 X 4 = -3 - 8 = -11

Notice I have made the mukltiplication be forde the subtraction.

However, if the sum is wrtitten as (-3-2)x 4 , then you do the brackets first .

( -5) x 4 = -20

It is definitely NOT -6 x 4
