The equation 1 - 2 = -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.
