What is bracket?

A bracket is like a special kind of parenthesis, but it’s even more powerful and helps us keep things organized when we’re doing math or writing long sentences.

Imagine you're playing with your toys, and you have two groups: one group of cars and one group of blocks. If you want to know how many toys you have in total, you might add them together like this: cars + blocks. But if you want to find out how many toy groups you have before adding them all up, you could use a bracket.

Think of a bracket as a toy box that holds some toys together so they stay in one group before you count them with the others. If your car group has 3 cars and your block group has 2 blocks, you might write it like this:

[3 + 2]

That means you’re keeping the cars and blocks inside the toy box (the bracket) before counting all your toys together.

Brackets help keep things neat when there are a lot of numbers or parts to a sentence, just like how your toy boxes help you keep your play area tidy!
