Asked by Emma
Use a calculator to simplify the expression.
8/2^3-2+4.1*2
When I used the calculator, I got 22.2
So then I used "PEMDAS" but got 7.53333...
But the answer is 7.2 can someone help please?

Plug the equation in in separate parts. Otherwise most calculators would change the steps up. Try this to start (8/(2^3))-2+(4.1*2). Remember the steps in solving an equation (power, parentheses, multiplication, division, addition, subtraction. In that order).
