*Everyone who works with computers is familiar with binary numbers. Whereas the decimal numbers we use everyday employ 10 distinct digits (0-9), binary numbers employ only 0 and 1. And while in decimal numbering each column counts for 10 times the column to the right, in binary numbers, each column counts for twice the preceding column. So instead of a 1’s place, 10’s place, etc., in binary numbers there is a 1’s place, 2’s place, 4’s place, 8’s place, 16’s place, 32’s place… displayed as follows: 32-16-8-4-2-1. *

*This watch uses binary numbers.*

** How The Whatch Works (example above):**

Two rows of 0’s and 1’s are displayed. 0’s represent zero; 1’s represent the binary system value:

The top row of 1 0 0 0 is, in decimal terms, equivalent to: 8 + 0 + 0 + 0 = 8. It indicates **hours**.

The bottom row of 1 0 0 0 1 1 is, in decimal terms, 32 + 0 + 0 + 0 + 2 + 1 = 35. It indicates **minutes**.

**The time is 8:35**
