## Solve in Base Systems

The equation 2 - 1 = 1 is represented in base 10 above. Here we show the same calculation but represented in other base counting systems. A base counting system is how many numbers are represented as group before advancing to the next digit. Example we normally use base 10 with numbers 0 to 9. When we add a 1 to the number 9 it becomes 10. For a base 3 system when a 1 is added to 2, it does not become 3 it becomes 10.

Base | Base Equation | Base Answer |

2 (binary) | 10 - 1 | 1 |
