The first slide on this activity has students writing an inequality. It is coded to read the inequality and interpret it on the graph. This means that there is a way to register inequalities.

This one is able to check that an inequality is correct.

The problem I am running into is this: I just want students to express a domain in inequality notion. I am wanting them to write it in an input box if possible, and check that for correctness. I know I can manually write in something like “solution1=#<x<#” but the problem is that if they dont write it exactly as I have it entered then it is read as incorrect. Dealing with the code embedded with graphs gets me lost, so I am stuck and not sure what to do. Been trying to figure this one out for a long time. I figured I’d ask one more time before letting this problem go.
