Its generally pretty good. It is able to walk through and explain its steps very well. The main problem with math is sometimes it will just do something that makes no sense. You basically have to redo it by hand to make sure it got the correct answer. But it gets it right significantly more often than not for anything Ive thrown at it recently, and so its still useful even it requires you to check its work. In the past, though, it was a complete waste of time to ask it to any math.
