thanks for the ideas Originally, I tried aligning the equations to the equal signs, but it increased the display width by about 30%. So, I had to choose from aligning the equal signs or a 30% font size. It still annoys me to see it centered, but half my traffic is from mobile. More explanations is a good idea. I think putting quizzes for students would work well for multiple choice questions. Numerical entry might be a bit more work. I'd have to get a library that evaluates strings into floats.
