I’m struggling to write what (in my mind) should be basic CL to help the following problem be self-checking on the dashboard. Any advice is appreciated!

The equation a + b = c could be true or false. Find new values of a, b, and c that make the equation true.

I currently have 3 individual math inputs on the slide, one for a, another b, last one for c and can’t get the CL to cooperate. I’m sure it’s user-error.

Any suggestions?
