(Definition) A modular congruence is a kind of equation (or a system of congruence, with at least one unknown variable) valid according to a linear congruence (modulo/modulus). With modulo, rather than talking about equality, it is customary to speak of congruence.

Solve Linear Congruences. Added May 29, 2011 by NegativeB+or- in Mathematics. This widget will solve linear congruences for you. The equation 3x==75 mod 100 (== means congruence), input 3x into Variable and Coeffecient, input 100 into modulus, and input 75 into the last box.
23 sie 2017 · $\begin{equation*} x_n = x_0 + \frac{nm}{\text{gcd}(a, m)} \; ( \text{mod} \; m) \end{equation*}$ I solved the following congruence $131x\equiv 21 \ (mod \ 77)$ and I got $ 56 + \frac{77n}{1}$ mod $77$, $77$ mod $77$ would be 0. $\endgroup$
1 lip 2024 · An equation of the form f (x)=b (mod m), (1) where the values of 0<=x<m for which the equation holds are sought. Such an equation may have none, one, or many solutions. There is a general method for solving both the general linear congruence equation ax=b (mod m) (2) and the general quadratic congruence equation a_2x^2+a_1x+a_0=0 (mod n).
1 lip 2024 · Using congruences, simple divisibility tests to check whether a given number is divisible by another number can sometimes be derived. For example, if the sum of a number's digits is divisible by 3 (9), then the original number is divisible by 3 (9). Congruences also have their limitations.
