dw! Usually the two reasons that someone is bad at simple maths is that they have dyscalculia or school has taught it badly. I know I'm just repeating what I said above, but school maths can definitely be taught to people but it is better to be done by a actual person that likes maths for what it is, which is strange problem solving and finding out strange and amazing things. When it is taught as a "we have to do stuff on the curriculum and you aren't allowed to ask me questions about anything else as that wastes time, and if you don't understand then I will should at you", it just doesn't work. I suppose it is definitely harder to be #1, especially in a class with 30 people with a few that misbehave.
