modular arithmetic - Way to speed up this modulo operation ...

WebIt is the thing we do to a number a so that when we multiply it by a number b it equals one. For example, the multiplicative inverse of 2 is ½ because: 2 * ½ = 1. We can do the same thing in modular arithmetic. Let’s ask ourselves: “What would I need to do to a modular equation to get it to equal 1?”. An example is: 2 mod 3 = 2 Web27 de may. de 2024 · Can we always do modular division? The answer is “NO”. First of all, like ordinary arithmetic, division by 0 is not defined. For example, 4/0 is not allowed. In modular arithmetic, not only 4/0 is not allowed, but 4/12 under modulo 6 is also not allowed. The reason is, 12 is congruent to 0 when modulus is 6. spring washer m4
