It looks like math functions are not fully supported when entering angles, specifically when editing linestring verticals. Please consider adding as this is a great feature.

Thank you!
This is now in the next release Pat - Easy Fix
It doesn't work with Ratios - only with % Slopes and Vertical Angles

Would it be possible to add the ability to use parenthesis for slightly more complex formals? Not so much in this area but in the alignment editor this would be very useful especially where you cant easily toggle between elevation and slope entry in the vertical tab.
example:
(10000-9000)*.5+121
