### Numbers for young learners to play with.

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.
