Okay kiddo, so the Ministry of Justice in Algeria is like a big group of grown-ups who make sure that everyone follows the rules and laws of the country.
You know how your teacher in school makes a list of rules for you to follow? Well, the Ministry of Justice does that for the whole country! They make sure that everyone knows the rules and that no one breaks them.
They also have special people called judges who listen to people's problems and decide what should happen, kind of like how your mom or dad might listen to you and your sibling's argument and decide who's right or wrong.
So basically, the Ministry of Justice in Algeria keeps everyone in line and helps solve problems when they come up.
