The TI-36X Pro calculator uses Equation Operating System
(EOS™) to evaluate expressions. Within a priority level, EOS
evaluates functions from left to right and in the following order.
3
% c
% i
<
1st
Expressions inside parentheses.
2nd
Functions that need a

and precede the
argument, such as
sin
,
log
, and all

items.
3rd
Fractions.
4th
Functions that are entered after the argument,
such as
x
2
and angle unit modifiers.
5th
Exponentiation (
^
) and roots (
x
‡
).
Note
: In Classic mode, exponentiation using the
G
key
is evaluated from left to right. The
expression 2^3^2 is evaluated as (2^3)^2, with
a result of 64.
In MathPrint™ mode, exponentiation using the
G
key is evaluated from right to left. The
expression 2^3^2 is evaluated as 2^(3^2), with
a result of 512.
The calculator evaluates expressions entered
with

and MathPrint™ modes. Pressing 3
