The modern approach to modular arithmetic was developed by Carl Friedrich Gauss
Carl Friedrich Gauss
Gauss also made important contributions to number theory with his 1801 book Disquisitiones Arithmeticae (Latin, Arithmetical Investigations), which, among other things, introduced the triple bar symbol ≡ for congruence and used it in a clean presentation of modular arithmetic, contained the first two proofs of the law ...
in his book Disquisitiones Arithmeticae, published in 1801. A familiar use of modular arithmetic is in the 12-hour clock, in which the day is divided into two 12-hour periods.
Who invented modulo?
M is called the sum of the numbers modulo N. Using notation introduced by the German mathematician Carl Friedrich Gauss in 1801, one writes, for example, 2 + 4 + 3 + 7 ≡ 6 (mod 10), where the symbol ≡ is read “is congruent to.”
Where did the word Modulo come from?
It is the Latin ablative of modulus, which itself means "a small measure." The term has gained many meanings over the years—some exact and some imprecise.
