I’m working on an activity that was previously handled in paper form. One of the questions asked requires an answer to be given to “three significant places”. Is there a neat general way to handle error checking for this type of numeric input?

You could try this borrowed from https://www.codegrepper.com/code-examples/python/how+to+round+to+3+significant+figures+in+python round(Number, SigFigs - 1 -round(floor(log10(|Number|)))) Here’s an example in the Desmos Calculator https://www.desmos.com/calculator/ardrybomi2
