**Operator precedence: **Each operator in C has a precedence associated with it.
- The precedence is used to determine how an expression involving more than one operator is evaluated.
- The operators of higher precedence are evaluated first.

** Precedence in Arithmetic Operators **:
An arithmetic expression without parenthesis will be evaluated from left to right using the rules of precedence of operators. There are two distinct priority levels of arithmetic operators in C.

- High priority * / %
- Low priority + -
