ELI5: Explain Like I'm 5

Group with operators

Okay kiddo, imagine you and your friends are playing a game where you can combine things to make new things. For example, if you have two toy cars, you can put them together to make a bigger car.

Now let's say you have three friends playing with you. You can work with them as a team to make even cooler things. You can call yourselves a group.

But there's more to being a group than just having a name. In a group, each friend has a special job they do. These jobs are called operators. One friend might be responsible for adding things together, another friend might be responsible for subtracting things, another for multiplying things, and so on.

When you work together as a group with operators, you can make even more complex things than when you play alone. For example, if you put together two toy cars with an operator that multiplies, you can make a miniature car factory!

In math, when we talk about groups with operators, we're usually talking about things called mathematical groups. These are groups of operations that follow certain rules, like multiplication or addition.

When you combine these operations with a group, you'll get a new, more complex operation. For example, if you combine the operation of adding with the operation of subtracting, you get a new operation called "additive inverse." This operation allows you to undo an addition operation by subtracting, and vice versa.

So there you have it, kiddo! A group with operators is a team of friends who work together to combine things using different special jobs, or operations. By doing so, they can make even cooler things than they could on their own.
