Why does addition work but multiplication not?

Gotta be something simple...

Thanks,

    They are working correctly. A and B are values with units. A*B would equal 12 in^2, which isn’t a length. You can either divide by “in” or use the “any” category, depending on your goals.

    I think it is because the result of multiplication gives an Area unit (in^2), not a Length unit. See if it works if you change the type to "Any" rather than "Length".

    Thank you! That pointed me in the right direction. Just learning about OS arithmetic. In my application, one of the variables is actually dimensionless. Changing to "any" resulted in the correct outcome.
    Much appreciated!

    If the variable is dimensionless, but it’s a real number (maybe a quantity or ratio), you should use the “number” option. “Any” is for any type which can’t fit in the first three choices.
