There is a certain order that we follow in doing any mathematical operation:
First we get rid of any operation within brackets, then we do multiplication and divisions and finally we do additions and subtractions.

We need to evaluate: 5x2x(-4) + 6:
So since we have no operations within brackets, then we will do the multiplications first (in their order) then the addition:
5x2x(-4)+6 = 10x(-4)+6 = -40+6 = -34

Now, we need to divide -34 by 2:
-34/2 = -17

The answer is: -17

the ratio of red apples to green apples was 7 to 4. If there were 56 green apples, how many re apples were there?

I think the answer would be 32 because 7x8 = 56 and 4x8=32

Hope this helps
