I want to add in a check for my students for this activity dependent on what value they type in. They are calculating related acute angles. But they can type any angle from each quadrant.
I want a simple subtraction verification

Quad 2
180- (angle)=related acute value

Here is the sample of the page that I’m hoping to fix.

Here you go. Come back to me with any questions you might have. I commented out an alternate where if a student is editing a cell there’s no feedback, but that’s not always desirable.

@Daniel_Grubbs That is so AMAZING!!! Thank you so much for taking the time out of your day to do that programming for me. It is perfect and exactly what I was hoping.
THANK YOU!!!

You’re very welcome. Just in general if you want to compare any type of calculation or non-integer or non-decimal values, you’ll need to either use numericValue() or simpleFunction().evaluateAt().
