#128#

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#
