The Decimal Number System has the following ten numerical symbols:
0, 1, 2, 3, 4, 5, 6, 7, 8, and 9.
When we add the number 1 to another number we get the next larger number. Example:
0 + 1 = 1, 1 + 1 = 2, 2 + 1 = 3, ... 8 + 1 = 9, 9 + 1 = 10,
10 + 1 = 11, etc.
What is really interesting is when we add the number 1 to the number 9. The answer
can no longer be shown as a single digit of 0 to 9. It takes two digits: 10. In
other words, instead of using a new symbol to represent ten, we start reusing 0 to
9.
