# Modular Equation Solver

## Modular equation solving calculator

Tool/solver to resolve a modular equation. A modular equation is a mathematical expression presented in the form of a congruence with at least one unknown variable.

### What is a modular equation? (Definition)

A modular equation is an equation (at least one unknown variable) valid according to a linear congruence (modulo/modulus).

For several modulus equations (non linear), this is a different calculation that can be solved with the tool solving the Chinese remainders problem available on dCode.

### How to solve a modular equation?

Enter the equation, the variables and the value of the modulo. The value of the modulo is global and applies to all equations.

Example: $$x+12 \equiv 3 \mod 5 \Rightarrow x = 1$$

The modular equation solver can not work with inequalities, only the equal sign is accepted to solve the equations.

### How to solve multiple equations?

Enter one equation per line or separate them with operator &&.

### How to write the congruence symbol ≡?

It is not necessary to write it (congruent) so that dCode can solve the equations, the equal sign = is enough.
