I do math visually, and am great at mental math.

I use a "sum of the parts" approach to almost everything I do, and the basic idea I explain to people is when I calculate tips and am accurate to the penny (most times...)

Bill is $100

tip is 20%

I see a diamond shape in my head with the $100 on top

$100

$10 $10

$120

I calcuate 10% of the total 2x with the 10%'s on the outer part of the diamond

the result is the bottom of the diamond

I'm curious as to why what you did is visual maths? Is it the fact you used a shape or just the fact you saw the numbers in your head and manipulated them as if looking at a computer screen - isn't this what everyone does ?

I'm going to go out on a limb here and probably leave myself open to ridicule and explain how I do maths. Me & my GF just compared the visual process involved in working out a very simple maths problem i.e. 15 -7

We both saw the numbers in our heads and visually manipulated them as if looking at a calculator but that's where the differences end.

She took the 15 and made it an even number by subtracting 1 = 14 , she then divided 14 by 2 to get 7 , then added the subtracted 1 to the 7 to get 8.

My approach was to visually see it as a sum written down with the 7 under the 15. I subtracted 5 from both numbers to give an easier sum 10 - 2 = 8.

Let the trashing commence
