Math questions almost always give you all the information you need to solve them, so don't get psyched out by the format of the question.  In this case, read the question and record the numbers as you go in order to figure out the correct answer, for example:

Take the number 32 and subtract 4. (One number is supposed to be four greater than the other) You are left with 28.  Divide it by two and you have 14 + 14.  Now add the original 4 back to one of those numbers and you have.... 18 + 14.
