Abbot and Costello

Costello is wrong. When you multiply 7 by 4 it is 28, not 7 by 14. Costello is wrong because when dividing you can't hold a number. Also when he added 14 he counted the one's place correct but not the ten's place correct. Another set of numbers you could use it 8x15=48. You could find this out very easily.


The problem would be set up like this: XY+X=Z


X= the multiplier


Y= the ones digit


X and Y have to be one of the digits 1-9.


For Example:


X=8


Y=5


8x5+8=48


8x15=48
