Question

To simplify 40 • 8 ÷ 4, which operation should be performed first?

Answer 1

It’s PEMDAS.
Note that multiplication and division go together, meaning whatever you perform, you’ll get the same answer.

The same goes for addition and subtraction. You can do anything first.

Multiplying first-
40•8 = 320
320/4= 80

Dividing first-
8/4=2
40•2=80

See? Both give us the same results :)

Answer 2

multiplication because in pemdas parentheses exponents multiplication division addition subtraction it's always left to right.
