If the fourth multiple of 3 is subtracted from the third multiple of 4 what is the difference

The difference is zero if you aren't insinuating that the term, "multiple" doesn't involve exponential factors.

3•4 = 12

4•3 = 12

12

-12

___

0

However, if you are saying one multiple of 3 involves exponential powers, Then 3^4 is 81 and 4^3 is 64

4^3 = 64

64 - 81 = - 17
