Answers to Questions

What is a modular equation? (Definition)

A modular equation is an equation (or a system of equation, 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.

For several modulus equations system (non linear), this is a different calculation that can be solved with the calculator 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.
