The TI-83 is designed to obey the standard order of operations when evaluating mathematical
expressions. **Click here for the TI-83/84 Plus order of operations. Operations are performed in this order (left to right at each level):
- Expressions within parentheses (innermost parentheses first)
- Functions that follow the argument (like 2!)
- Exponents and roots
- Functions that precede the argument (like log(2) or negation)
- Multiplication and division, including implied multiplication
- Addition and subtraction
A complete list of the order of operations is provided in the Guidebook
(see EOS).
The real key to avoiding errors when evaluating expressions is a liberal and careful use of
parentheses. Parentheses allow you to control which operation is performed first, and to enter
an expression so that the TI-83 will correctly interpret it. As a general rule of thumb, use
parentheses whenever you are in doubt about the order of operations. |
