hahahahahaha! XD (I was kidding!)
I was refering to COUNT, really. And there are strategies to count that even allow to express the number you want to reach directly in our ten-digit positional numeration system...
An easy example of this is... ...
try to count how many smileys are there in following line:
☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺.
If you display the smileys as above, you'll have to count them one-by-one to get the answer: there are 28 of them...
But if you display them in other manners, it could be easier to deduce it with just one glance:

groups of a hundred groups of ten five units
In fact, this idea is the one behind the invention of decimal system. Every order of units follows the pattern of an (usually incomplete) rectangle with five rows and two columns of groups of an order below, or just elements in the easiest case.
