The correct answer to this question is this one: "72 + 25"

This is how being revised:
first, the sign of 72 is positive (by default) because there is no "minus" sign.
Second, the sign of 25 is negative because of the negative sign.

72 - (-25) is just like saying 72 - 1 * (-25)
which means that -25 is multiplied with -1. Negative times negative is positive.
