Before 1600 BC number system is invented. There were several proofs to prove this. On that time number system is represent as symbol.After that roman number system evolved. On the basis of roman number system we got 1 to 9 numbers.

But what after it? Credit goes to Indian mathematician Aryabhatta to invent 0. We get so many numbers to speak up now. We derive whole number system in other two type :
(1) Cardinal: 1, 2, 3, 4 etc.
(2) Ordinal: 1st, 2nd, 3rd etc. (Word “Ordinal” is from word “order”)

In Computations, binary is use as language for machines too. Any electronic/electrical device having coded chip in it called Microcontrollers nowadays.

In binary 0 and 1 are used. 0 means success and 1 means failure in arithmetic meaning. Computations is differ than calculation.
Calculation is process where 1 and 1 is 2 (cause 1+1). But in Computation logic involves and having multiple answers as 11, 1, 0, 2 (cause no operation is define).

Interesting!!! Isn’t it?
