Hmmm I guess this where my lack of math ability comes in but. I didn't realize you could only compare by subtraction.

When I was a kid back on the Stone Age, it was common to get mental tests where you just has to give the answer correctly.

What is the sum of a and b meant ADD them
What is the difference meant Subtract
What is the product meant Multiply
What is the quotient meant Divide

I think that is the meaning of 'difference' there, Irene.
