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#
