My basic skills at mathematical calculation are terrible. I often count on my fingers for basic addition and subtraction, and memorizing multiplication tables was beyond me. I often turn numbers around, but can identify identical strings of numbers (like picking out duplicate addresses, or so forth) based on the shapes of the symbols. I'm very good, also, at mentally calculating angles (think bank-shots in pool) and at visualization of three dimensional objects, including projecting two dimensional renderings into three dimensions in my head. It has only been recently that I realized that most people can't take a two dimensional drawing, expand it, then rotate it mentally. I'm not always flawless at this, but I can do it pretty accurately most of the time. I'm a verbal/visual learner.
Isn't it odd that you add and subtract on your finger but you basically are doing subtraction in less that 1 sec when it's presented visually? I mean you're not coming up with an exact value but you are determining that there is more in one group than another, that's basically subtraction. One of each color cancel each other out leaving some from one group with nothing to cancel them out. I wonder if it be easier for you to do arithmetic if you visualized the numbers as groups of dots.
