-3(5)^2-(-2)(-8) simplify

To do this, we're going to use the order of operations (PEMDAS):

P - Parentheses

E - Exponents

M - Multiplication

D - Division

A - Addition

S - Subtraction

First let's do parentheses, there isn't anythig in parentheses we need to simplify, so we can skip this step.

Next let's look for exponents. I see we have a
5^2 so let's replace that with
5^2=25:


-3(25)-(-2)(-8)

Now let's look for multiplcation. We know that things that are right next to eachother in parentheses represent multiplcation, so let's simply this more:


-3(25)=-75


(-2)(-8)=16


-75-16

And now we're left with a simple problem we know how to solve.

Answer:
-91

Hope this helps!
