No you don't start at 0, you start in the middle.

I know, the middle would be 7. 14 floors total.

14

7th floor being his starting point - and if thats the MIDDLE then its 14 floors. (or 13 if you calculate the 7th being the middle, then 6 above and 6 below.)

I came up with 8 floors and when it says middle floor that means there is 7 floors going up and 7 floors going down so 15 floors

****DRUM ROLL***




























15 floors is the correct answer.....now figure it out. I finally just figured it out, after my husband explained it to me. Don't ask me to explain it though

Apparently 5th grade math is rocket science

That's the conclusion I came to. I can only guess that most of the students figured it was the 8th floor of a 16 story building, but for a single floor to actually be in the middle of a building it would have to have an odd number of floors.

The child is 11, 5th grade math not rocket science!

That's hardly beyond the comprehension of a 5th grader. If there were an even number of floors the middle point would be between floors. For a single floor to be "in the middle" it has to be an odd number of floors. He obviously got on at the 8th floor, that's the easy part, but the 8th floor isn't in the middle of a 16 story building, it's in the middle of a 15 story building.
