I can't count.
Well, okay, I can count. I can even sometimes subtract and multiply. And I can still remember Pythagoras' theorem and how to work out the area of a triangle. But that's about it.
I've always been really bad at Maths. I have no idea why. I was always pretty good at every other subject in school, but when it came to Maths as soon as the teacher started talking I would zone out and happy music would start playing in my head (I often find that I can hear the theme from The Magic Roundabout when I start to zone out. I wonder if there is a word for that kind of crazy).
I think I only passed my GCSE maths exam because my mother sat me down the night before and taught me long multiplication and division and how to work out percentages. I remember opening the paper and the first question being a sum about working out VAT. I was so happy.
But yeah, after my GCSEs I dropped that subject like a hot coal, and never took anything maths-based again.
