-- plural is parentheses
Parentheses are marks used to group operations.^{[1]}
Parentheses are always used in pairs. The left parenthesis looks like: (. The right parenthesis looks like: ).
The parentheses are used to group operations in math. For example, the expression 5·4+2 evaluates to 22. Using the order of operations, we first multiply 5 and 4 to get 20, and then add 2 to get 22.
However, if we use parentheses to write the expression as 5·(4+2), the value of the expression changes. The parenthesis tells us to add 4 to 2 before multiplying by 5. Adding 4 and 2 gives us 6. When we then multiply by 5 we get 30.
