Order of operations

The TI-30XPlus MultiView™ 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.

1st Expressions inside parentheses.

2nd Functions that need a ) and precede

the argument, such as sin, log, and all

R³´P menu items.

3rd Fractions.

4th

Functions that are entered after the

argument, such as x

and angle unit

modifiers.

5th Exponentiation (^) and roots (

‡).

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.

30XPlusMV_OM.flpgl Page 13Friday, November 14, 2014 1:57 PM

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 F and a from left to right

in both Classic and MathPrint™ modes.

Pressing 3 F F is calculated as (3

Fractions

P % @ d 1 % ãf³´dä

In the MathPrint™ mode, fractions with P can include

real and complex numbers, operation keys (T, V,

etc.), and most function keys (F, %, _, etc.).

In Classic mode, fractions with P do not allow

operation keys, functions, or complex fractions in the

numerator or denominator.

Note: In Classic mode, only number entries are

supported when using P. Fractions in Classic mode

are shown with a double-thick fraction bar (for

example, ). The numerator must be an integer,

and the denominator must be a positive integer. To

compute more complex expressions (functions,

variables, complex numbers, etc.), use W along with

( and ).

The calculator defaults output to improper fractions.

Results are automatically simplified.

• P enters a simple fraction. Pressing P before or

after a number can result in different behavior.

Entering a number before pressing P makes that

number the numerator.

To enter fractions with operators or radicals,

press P before you enter a number (in

MathPrint™ mode only).

• In MathPrint™ mode, press $ between the entry

of the numerator and the denominator.

30XPlusMV_OM.flpgl Page 16Friday, November 14, 2014 1:57 PM

• In Classic mode, press P between the entry of

the numerator and the denominator. The fraction

bar will appear thicker than the division bar.

• Pressing % # from any MathPrint™ level,

including the denominator or a lower limit, places

the cursor in the history. Pressing enter will then

paste the expression back to that MathPrint™

level.

- To paste a previous entry in the

denominator, place the cursor in the

denominator, press % # to scroll to the

desired entry, and then press < to paste

the entry to the denominator.

- To paste a previous entry in the numerator

or unit, place the cursor in the numerator or

unit, press # or % # to scrollto the

desired entry, and then press < to paste

the entry to the numerator or unit.

• % @ enters a mixed number. Press the arrow

keys to cycle through the unit, numerator, and

denominator.

• d 1 converts between simple fractions and

mixed-number form (4n/

Errors

When the calculator detects an error, it returns an

error message with the type of error. The following list

includes some of the errors that you may encounter.

To correct the error, note the error type and determine

the cause of the error. If you cannot recognize the

error, refer to the following list.

Press - to clear the error message. The previous

screen is displayed with the cursor at or near the error

location. Correct the expression.

The following list includes some of the errors that you

may encounter.

0<area<1 — This error is returned when you input an

invalid value for area

invNormal

ARGUMENT — This error is returned if:

• a function does not have the correct number of

arguments.

• the lower limit is greater than the upper limit.

• either index value is complex.

BREAK — You pressed the & key to stop evaluation of

an expression.

CHANGE MODE to DEC — Base n mode: This error is

displayed if the mode is not DEC and you press ,

I or .

COMPLEX — If you use a complex number incorrectly

in an operation or in memory you will get the

COMPLEX error.

DATA TYPE — You entered a value or variable that is

the wrong data type.

• For a function (including implied multiplication) or

an instruction, you entered an argument that is an

invalid data type, such as a complex number

where a real number is required.

• You attempted to store an incorrect data type, to

a list.

• Input to the complex conversions is real.

• You attempted to execute a complex number in

an area that is not allowed.

DIM MISMATCH — You get this error if

• you attempt to store a data type with a dimension

not allowed in the storing data type.

DIVIDE BY 0 — This error is returned when:

• you attempt to divide by 0.

• in statistics,

= 1.

DOMAIN — You specified an argument to a function

outside the valid range. For example:

• For

áy:

= 0 or

< 0 and

is not an odd integer.

• For

and

= 0;

< 0 and

is not an integer.

• For áx:

30XPlusMV_OM.flpgl Page 73Friday, November 14, 2014 1:57 PM

EQUATION LENGTH ERROR — An entry exceeds the

digit limits (80 for stat entries or 47 for constant

entries); for example, combining an entry with a

constant that exceeds the limit.

Exponent must be Integer — This error is returned if

the exponent is not an integer.

FORMULA — The formula does not contain a list name

(L1, L2, or L3), or the formula for a list contains its own

list name. For example, a formula for L1 contains L1.

FRQ DOMAIN — FRQ value (in 1-Var and 2-Var stats)

< 0.

Input must be Real —This error is displayed if a

variable pre-populates with a non-real number where

a real number is required and you move the cursor just

past that line. The cursor is returned to the incorrect

line and you must change the input.

Input must be non-negative integer — This error is

displayed when an invalid value is input for x and n in

the DISTR menus.

INVALID EQUATION — This error is returned when:

• The calculation contains too many pending

operations (more than 23). If using the Stored

operation feature (op), you attempted to enter

more than four levels of nested functions using

fractions, square roots, exponents with ^,

, and 10

• You press < on a blank equation or an

equation with only numbers.

Invalid Data Type — In an editor, you entered a type

that is not allowed, such as a complex number or as an

element in the stat list editor.

30XPlusMV_OM.flpgl Page 74Friday, November 14, 2014 1:57 PM

INVALID FUNCTION — An invalid function is entered in

the function definition in Function table.

Mean mu>0 — An invalid value is input for the mean

(mean=mu) in

poissonpdf

poissoncdf

Number of trials 0<n<41 — Number of trials is limited

to 0<n<41 for

binomialpdf

and

binomialcdf

OP NOT DEFINED — The Operation m is not defined.

OVERFLOW — You attempted to enter, or you

calculated a number that is beyond the range of the

calculator.

Probability 0<p<1 — You input an invalid value for a

probability in DISTR.

sigma>0 sigma Real — This error is returned when an

invalid value is input for sigma in the DISTR menus.

SINGULAR MAT — This error is displayed when:

• The SinReg instruction or a polynomial

regression generated a singular matrix

(determinant=0) because it could not find a

solution, or a solution does not exist.

STAT — You attempted to calculate 1-var or 2-var stats

with no defined data points, or attempted to calculate

2-var stats when the data lists are not of equal length.

SYNTAX — The command contains a syntax error:

entering more than 23 pending operations or 8

pending values; or having misplaced functions,

arguments, parentheses, or commas. If using P try

using W and the appropriate parentheses.

TOL NOT MET — You requested a tolerance to which

the algorithm cannot return an accurate result.

30XPlusMV_OM.flpgl Page 75Friday, November 14, 2014 1:57 PM

TOO COMPLEX — If you use too many levels of

MathPrint™ complexity in a calculation, the TOO

COMPLEX error is displayed (this error is not referring

to complex numbers).
