Definition:
The denary (or decimal) numbering system is the most widely used in the world. It has a base of 10 and uses the numerals 0,1,2,3,4,5,6,7,8,9. It's thought that we adopted a base 10 system because we originally learnt to count using our fingers.
Even though computers are based on the binary system, they most commonly convert numbers into the denary system to make them easy to understand by humans.
