Question

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

Answer 1

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!
