Answer 1

Hello Shaun,

For PE(MD)(AS), multiplication and division are at the same level, just as with addition and subtraction, which is why I have put each pair in parentheses.  Which ever comes first from left to right out of those pairs, you do first.

 

So,

9 - (12)(-4) ÷ 8

= 9 - (-48) / 8, by doing the multiplication,

= 9 - (-6), by doing the division,

= 9 + 6, since subtracting a negative is adding,

= 15.

 

I hope the above helps, and thank you for posting the question.

Answer 2

9-(12)(-4)÷8

use the order of operations:

grouping symbols

exponentiation

multiply and divide from left to right, whichever occurs first

add and subtract from left to right, whichever occurs first

9-(12)(-4)÷8

9-(-48)÷8

9-(-6)

9+6

15  (subtracting a number is the same as adding its opposite)
