I gave up having ChatGPT do the math when explaining/doing homework with my kids. I don't have time to proof its mistakes. As such my prompt for it when dealing with math is along the lines of:

"Solve <description of the problem, usually 2 to 5 phrases>. Use WolframAlpha and give me the link".

Then I just copy the link it's spitting out and I go myself to WolframAlpha for the correct result.

ChatGPT is great at understanding the description of the problem in plain language and writing the WolframAlpha input I need. It shortens greatly my time to verify my kids exercises since WolframAlpha's input box is not that great.
