Okay kiddo, have you ever been in an emergency or seen something really bad happen and needed help right away? That's when you call 1-1-2. It's a special phone number that connects you to people who can help you when you're in trouble.
The first number, 1, is for emergencies like if someone is hurt or there's a fire. You call this number if you need help right away and can't wait.
The second number, 1, is for the police. If you see someone doing something wrong or someone is being mean or hurting other people, you can call this number to get the police to come and help.
The third number, 2, is for the ambulance. If someone is really sick or hurt, you can call this number so that doctors and nurses can come and help them.
