What are people who are poor at mathematics usually good at? I'm assuming, of course, that you're good at something else to make up for it.

I just cannot fathom the concept of negative numbers. You cannot have less than nothing of something. if you have a tooth pulled, you aren't negative 1 tooth, you simply have 0 tooth in the spot formerly occupied by 1 tooth. you can have 1 tooth minus 1 tooth but that leaves you with 0 tooth. you cannot have -2 tooth from the spot occupied by a single tooth thus resulting in -1 tooth! argh!
Maybe try looking at it in terms of debt? If you owe somebody $2, you can think of it as literally having $-2 in your wallet right now. E.g.
- You have a $10 note (+10)
- You owe somebody $2 (-2)
- So even if you have a $10 note, only $8 of it is yours to spend if you want enough left over to return the money. Please don't try to tear off 80% of the note, though.
