The Decimal System.
You are undoubtedly familiar with the decimal numbering system, which is why we will start with it.
After all, starting with something you already know will make it easy to introduce the concepts we will use in the other numbering systems.
The Decimal system is what you use everyday when you count. Its name is derived from the Latin word Decem, which means ten.
This makes sense since the system uses ten digits:
0, 1, 2, 3, 4, 5, 6, 7, 8 and 9.
These digits are what we call the symbols of the decimal system.
Since we have ten symbols, we can count from 0 to 9.
Note that '0', even though it often means 'nothing', is a symbol that counts!
After all, you need a numeric way to say 'nothing'.
When you want to count past what your simple symbols will allow, you combine multiple digits.
Thank you very very much!
