I've done that a bit. I can't count stuff very well, lol. Dunno why. If at work, i'm presented with 12 cans of summat, i have to arrange them to be easily counted. Also, if I get a reduced item, which normally begins, 91000000, but sometimes 910000000, and sometimes different still, it's difficult to make myself count the zeros. I normally press the 0 button, and count each one. But to look at them and know how many there are just by looking, i can't do it very well. Same with maths, when I do maths in my head it feels like such a challenge to keep all the numbers in my head at once. It's a weird sensation, I can't describe it except for it being a challenge. Dyscalculia, is it? haha I used to be badass at spelling, I can spell most words, even words I've never seen before. But recently, sometimes I catch myself hesitate a little. Today, I very nearly even used the wrong 'your'. When I'm draconian about that, even with myself.
