The numbers are visually designed

to have their value appear in

the geometry, or logically somehow.

Note the numbers five and higher

are sums of the lower numbers.

For example the #7 is a square

around a triangle, hence 4 + 3,

or #7. Have fun. Enjoy.

Smart!

But why can't 1 be just | and 2 be || ?

Thanks.

Well I suppose they could be | and ||, but then

if you use them a lot, you might confuse the | with the letter I,

and also if two |'s get too close together, then eleven might

be thought to be 2. That's what I was thinking I guess.

Here's somemore numbers from

ten to fifteen.

These are just for fun.

Not much logic in

these except ten and

fourteen.

A cube has 8 points and

6 sides, making 14.

A person has ten toes.
