Please help me to solve this equation.

Question

Here is the question:

a+b=c implies ac<+>bc = ab. Use this to create three reductions involving integers only. (E.g. 1+2=3, so 3<+>6=2.)

Answer 1

Heck, they gave you an example, so that makes it easy. Just pick any values for a,b,c:

9-3=6 ==> 9*6<+>-3*6=9*-3 or 54<+>-18=-27

Who cares what <+> really means?

Answer 2
