It can't handle trigonometric identities and any form of calculus at the same time without fucking it up. Also abstract stuff like symmetry groups, nope! And anything which involves vectors is a mess. The big problem is it confidently answers the questions utterly wrongly. This is stuff I expect a basic mathematics undergrad to be able to work out in their first or second year.
