Concept of figures

One of uncivilised people used to count the number as 1, 2, many. For them three and one hundred didn't make difference. They would have agreed to exchange three silver coins and almost unlimited land.

We ordinary people grasp the numbers of one to nine in each different figures. But one genius can grasp the number in each different shapes, and he can calculate answer by multiplication done by their shapes. So he can automatically calculate like 78623 X 1984778 by forming two figures together.

I assume some might be almighty.
