WebModular arithmetic is basically doing addition (and other operations) not on a line, as you usually do, but on a circle -- the values "wrap around", always staying less than a fixed number called the modulus. To find, for example, 39 modulo 7, you simply calculate 39/7 (= 5 4/7) and take the remainder. WebIn modular arithmetic we do not have a division operation. However, we do have modular inverses.

WebThe notation for modular arithmetic includes two symbols, the congruence symbol ( ≡ ≡) and the mod. Both of these symbols together indicate that the equation is not an exact equality but a modular condition and the mod indicates the specific modulus we are using. WebOct 21, 2024 · In mathematics, modular arithmetic is a system of arithmetic for integers, where numbers "wrap around" when reaching a certain value, called the modulus. The modern approach to modular arithmetic was developed by Carl Friedrich Gauss in his book Disquisitiones Arithmeticae, published in 1801.
