Simplify the following expression.

4 (20 + 12) : (4 - 3)

can you show me how to work this out

The answer would be 128.

First you would do 4 (20) + 4 (12) when you solve that you will get 128

4*20 = 80 + 4 (12) or 48

Next you would do (4-3) which is 1

After simplifying both sides, the problem would then be 128 divided by 1 and you would get 128 as your answer

4 (20+12) / (4-3)

4 (32) / 1

128/1 = 128

Have a great day!
