I am not good in math, so I can not figure out the answer. Your explanation is good, but you need to give me the final answer.

Re: Rewrite the expression without using the absolute value symbol.

After a very long thinking, now I get it. The answer would be just 4 - pi. And if if we reverse the question like this |pi - 4|, pi - 4 will be less than zero. Therefore, the answer will be -(pi - 4) = 4 - pi.

What if want the answer, but we do not know the value of X, like this?

|4 - X| = ?
