It is important to understand that operators have a precedence, but it is not essential to memorize the precedence.

---

New Term: Precedence is the order in which a program performs the operations in a formula. If one operator has precedence over another operator, it is evaluated first.

---

Higher precedence operators "bind tighter" than lower precedence operators; thus, higher precedence operators are evaluated first. The lower the rank in the following chart, the higher the precedence.
