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?

**MathMat**, Thursday, January 17, 2013 at 10:59pmPlug 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).
