Hector works on the 4th floor of a high rise building. He needs to go up 9 floors to get to the cafeteria for lunch, and then go down 5 floors to attend a meeting. On what floor does the meeting take place?
So, start at 4. You know that he needs to go up floors, so it would be 4 + 9, which is 13. He is now on the 13th floor. You also know, that he needs to go down 5 floors. So the equation would look like this: 4 + 9 - 5 = ? so, 13 - 5 is 8. The meeting is on the 8th floor.
