Formula Question with Negative Numbers

[Mperrypchs]

Can the formula question type handle negative numbers for multiplying and dividing questions? I have been trying to put in simple multiplication questions and can't seem to get negative numbers to work.

I have done (`x`)(`y`) and then set x to be 1 to 12, then y to be -12 to -1. I then get an error for Number of Solutions. Has anyone had success with negative numbers? 

TIA

I tried putting in exactly what you have and there was no issue at all. Have you tried switching the variable values so that X is the negative? Did you double check that you put backticks rather than apostrophes? It's weird, as it recognizes both variables, so I am not sure why it says there are no possible solutions.
