ELI5: Explain Like I'm 5

Consideration

Consideration is an important part of making a deal. It's like a promise or exchange between two or more people, or groups, that each person agrees to. For example, say you want to buy a toy from a store. You give the store some money for the toy, and the store gives you the toy you want. That's an example of consideration - each person agrees that they will give something to get something in return.
