I thought this video was very funny and interesting. However, I could not think of a mathematical response for this, except that the division was done backwards. Some other numbers that work for this are:

6,12=18

5,14=25

4,15= 24

3,17= 24

I didn't really use a method to figure this out, I kind of just guessed and checked.
