128

Explanation:

Using the order of operations, do the operations inside the parenthesis first, followed by multiplication/division and finally addition/subtraction.

Red operators indicate the current step.

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

=4(32)-:(1)

Multiply next (from left to right)

=128-:1

This is simply 128
