I just noticed with much hilarity that my occupation in my profile was set to 'accounting'. Hahhaaaaa. No. I wish. Then I might have some money.
But no, in actual fact I am numerically challenged. I may in fact have discalculia, numerical dyslexia. To add, say, 35 and 17 I have to write the sum down in my head. Especially if someone is there, I become surrounded in a red fog of confusion if I have to calculate. For example, last weekend, when I had to give people change of a fiver, I had trouble working out what to give back on €1.50. Really. My brain shuts down and nothing makes sense.
