Lets start from the top of the list and work out way down.
#124-3*(7+5^2)#
We see parentheses! Now we must simplify what's inside of them. We also see exponents. Let's simplify the exponents, and then finish simplifying inside the parentheses:
#124-3*(7+25)#
#124-3*(32)#
Now, moving down the list, we come across parentheses. Be careful, we are multiplying
#124 + (-96)#
#124 - 96#
Now subtract!
#28#
