Wrong maths, you say?

Yes. If I want to know what 1+2 equals, and I throw a dice, there's a chance I will get the correct answer. If I do, that doesn't mean it knows how to do Maths. Also, notice where it said "Here's the calculation", it didn't actually show you the calculation? e.g. long multiplication, or even grouping, or the way the Chinese do it. Even a broken clock is right twice a day. Even if AI manages to randomly get a correct answer here and there, it still doesn't know how to do Maths (which includes not knowing how to count to begin with)
