Order of Operations

The TI-36X üuses EOSè (Equation Operating

System) to evaluate expressions.

Order	Evaluation
1st	Expressions inside parentheses.
2nd	Functions which need a ) and precede the
	argument, such as sin, log, and all R/P
	menu items; Boolean Logic NOT and 2’s
	complement.
3rd	Fractions.
4th	Functions that are entered after the argument,
	such as x2 and angle unit modifiers (éêër g);
	metric conversions.
5th	Exponentiation (^) and roots (x‡).
6th	Negation (L).
7th	Permutations (nPr) and combinations (nCr).
8th	Multiplication, implied multiplication, division.
9th	Addition and subtraction.
10th	Boolean logic AND.
11th	Boolean logic XOR and OR.
12th	Conversions (4Ab/c/d/e, 4F/D, 4DMS).
13th	Vcompletes all operations and closes all
	open parentheses.

You can change the order of operations by enclosing expressions in parentheses.
