What is the difference between parentheses and brackets in math?

Parentheses are the symbols that curve forwards and backwards. When numbers and operations are inside the parentheses, it forms a group and it tells you what to do first in a math problem.

Brackets work exactly the same way as parentheses do. Brackets have a shape that looks more boxy but they mean exactly the same thing. Usually, you will see parentheses more frequently than brackets, but brackets are used a lot too.
