What apps provide annotated steps of calculations?

I have mathematical formulas that I need to calculate and my question is:

What apps provide a calculation’s steps with explanations?

In Wolfram Alpha and Symbolab, I'm getting the issue as:

To clarify, I'm not asking about how to do it or how easy it is. I'm asking what resources can be used and how they could be helpful in this use case.
