**IMPORTANT EE RULES: **

**Count = Integers | Scale = Real Numbers | Most mathematical functions can only be done with Scale (dimensionless) values. | Display units (mm or inch) are considered as separate elements in the equation by the Editor**

As Stefan said*"So a sqrt of 25mm² will work because of 5*5 and mm*mm... but ask yourself what is the square root of mm?"*

So distance values need to be converted to scale (dimensionless) values, which you do your desired function on, then convert the answer back into a distance value

V1 (scale) = [D1] 3.5 (mm) / 1 (mm) = 3.5/1 * mm/mm = 3.5 * 1 = 3.5 | V2 (scale) = [D2] 3.12 (mm) / 1 (mm) = 3.12/1 * mm/mm = 3.12 * 1 = 3.12 | V3 (scale) = math function(V1-V2) | D3 (distance) = [V3] 0.61644 * 1 (mm) = 0.616 mm

The equation**TYPE **is very important.
