Evaluate.

22. (absolute value) 2-pie

I'm sorry, but I don't understand what the above is meant to indicate...? To learn how to format math as text, please try here. Once you have reviewed the basics, please reply with clarification. For instance, what is inside the "absolute value"? Is the "2" which follows the absolute value meant to indicate squaring, or something else? Is the subtracted value really the product of $\displaystyle \pi$ (that is, "pi") and $\displaystyle e$ (that is, "e"), or did you mean just "pi"?

When you reply, please show all of your work so far, and also clarify how this exercise requires calculus, rather than merely being a simple pre-algebra simplification. Thank you!

Do you mean that problem 22 is to evaluate $\displaystyle |2\pi|$? Do you know what $\displaystyle \pi$ is? Do you know what the "absolute value" is?
(By the way, the standard transliteration for $\displaystyle \pi$ is "pi", not "pie".)
