Starting from the right and with the thumb, we assign the values like so:

Thumb = 1

Index finger = 2

Middle finger = 4

Ring finger = 8

Baby finger = 16

A fist = 0

To make 13 in binary, you would need to keep raised the fingers that all add up to 13.

in this case we would keep up the ring finger (8), the middle finger (4) and the thumb

(1) as they all add up to 13.

Try doing 30.

You would hold up all fingers except for your thumb!

It’s really simple and allows you to count up to 31 on one hand!

To make the binary numbers bigger, simply follow the pattern onto the next hand,

Starting with the baby finger of your left hand:

Baby finger = 32

Ring finger = 64

Middle finger = 128

Index finger = 256

Thumb = 512

Incorporating both hands allows you to count to 1023!

What fingers would you hold up to get 444? ?
