# Programming: find the total possible combinations of three variables?

I have three variables in a programming function, and a 4th variable depends on these. I have to test the dependent variable against all combinations of the three variables:

- Var A: 2 possible values
- Var B: 3 possible values
- Var C: 5 possible values

The order of the three variables is not important. How can I find the number of possible combinations of these three variables, so that I know how many tests would need to be written?

**Note:**
I have asked a regarding this:

Now I know that there are 30 combinations of these three variables (2x3x5), but how do I draw this in table form?

If each variable was binary, I could draw a truth table: 000, 001, 010 etc. But is there an equivalent system for the combination I have detailed here?

Thanks

Brian
