Has anyone tried using chatGPT to solve and explain math questions? How bad were the results?

After doing my maths quiz yesterday I had somehow got three questions wrong: 1 because I’m an idiot, the second because there was a dumb looking equivalent fraction as an answer, and the third I still can’t see how it’s wrong.

Anyway the question was a=3-i e=-1+i, then (|a|/ē)(|e|ā) is? and after chucking it into wolfram alpha and getting the same result I had calculated, I chucked it in chatGPT.

It had no worries recognising and getting the conjugate and modulus and doing arithmetic with these complex numbers but it couldn’t simplify a surd. First it said sqrt(10)=5sqrt(2). Then I prompted again telling it sqrt(10)≠5sqrt(2), it agreed then spat out the exact same mistake. Then I told it not to simplify the surd at all and it went “cool, sqrt(10) is 5/2”.

Has anyone else seen chatGPT get it comically wrong in pretty simple maths?
