Binary Finger Counting: 1 to 7
This Binary Finger Counting site is part of my overall binary tutorial. If you're confused by this Finger Counting tutorial, please visit that tutorial first.

The thumb represents the value 1, the index is double that, so it's 2, and the middle is double the index, so it's 4, etc. This is key to understanding and fluently counting in binary on your fingers.

To make the number 3 for instance, you have to combine a 2 finger and a 1 finger (2+1=3).
