I also asked it to prove some elementary theorems. Didn't really have a proper unterstanding of definitions. But it's actually fairly good at solving simple word problems. Something like: assume you have 3 bottles, each with a capacity of two liters, and each filled to 20% of its capacity. Say you have a fourth bottle with the same capacity und you pour the content of each of the first three bottles into the fourth. To what capacity is the fourth bottle now filled. And it comes up with the correct answer, which is absolutely astounding.
