# Number Shape System

The number shape system is a type of Mnemonic Peg System where digits are assigned mnemonic images based on the shape of the number. For example, the number 1 might have an image of a candle, because 1 looks like a candle.

Some possible number shape images are:

- 0 = ball, egg, doughnut, ring
- 1 = candle, stick, spear
- 2 = swan
- 3 = butterfly, handcuffs, heart, trident
- 4 = flag, sailboat, chair
- 5 = hook, snake, Superman, seahorse
- 6 = elephant's trunk, golf club, cherry, combination lock, curled snake
- 7 = boomerang, axe, scythe
- 8 = snowman, hourglass
- 9 = balloon on a string

There is also a way to use number shapes with 2-digit numbers and binary numbers.
