-3%5E2-5%284-2%284-9%29%29 Start with the given expression.


-9-5%284-2%284-9%29%29 Square 3 to get 9


-9-5%284-2%28-5%29%29 Subtract 9 from 4 to get -5


-9-5%284%2B10%29 Multiply -2 and -5 to get 10


-9-5%2814%29 Add 4 to 10 to get 14


-9-70 Multiply -5 and 14 to get -70


-79 Subtract 70 from -9 to get -79


So -3%5E2-5%284-2%284-9%29%29=-79
