Answers to Questions

How to solve a modular equation?

Enter the equation, the variables and the value of the modulo (which is global for all equations).

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

If you have several equations with several modulo, see the problem of Chinese remainders.

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

How to write the congruence symbol ≡?

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

How to solve multiple equations?

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