the power of 10. The calculator notation, â, designates the "x10" part of
the number without using extra parentheses. The calculator then follows
the order of operations as expected when using SCI or ENG notation.
This notation, â, is not typically accepted on homework and exams, and
written results should use the standard notation, for example, the
1.234567 x 10
4
.
• If you select NORMAL notation, but the answer cannot display in 10 digits
(or the absolute value is less than .001), the TI-84PlusCE expresses the
answer in scientific notation.

• Coordinates on a graph
• The Tangent( DRAW instruction equation of the line, x, and dy/dx values
• Results of calculated operations
• The regression equation stored after the execution of a regression model
RADIAN DEGREE
Angle modes control how the calculator interprets angle values in trigonometric
functions and polar/rectangular conversions. The RADIAN or DEGREE setting
will display in the status bar.
RADIAN mode interprets angle values as radians. Answers display in radians.
DEGREE mode interprets angle values as degrees. Answers display in
degrees. Polar complex number arguments are always interpreted in radians.

FUNCTION graphing mode plots functions, where Y is a function of X.
PARAMETRIC graphing mode plots relations, where X and Y are functions of T.
POLAR graphing mode plots functions, where r is a function of q.
SEQUENCE graphing mode plots sequences.Three sequences are available:
u, v, and w as functions of n.
THICK DOT-THICK THIN DOT-THIN
Line Style: Graphs as:
THICK
Thick line style (default). More pixels displayed around a
plotted point (pixel).
DOT-THICK
Large dot plotting. (3x3 pixels) Equivalent to DOT on earlier

THIN
Thin line style (graphing per pixel).
DOT-THIN
DOT display is 1 pixel per dot graphed.
Note: You can change individual line styles in the Y=editor.
THICK plotting mode resets all Y= line styles to a thick line connecting each
point calculated for the selected functions.
Note: The THICK plotting mode on the TI-84 Plus CE is equivalent to the
CONNECTED plotting mode on the TI-84 Plus family of graphing calculators.
DOT-THICK plotting mode resets all Y= line styles to a large dot and plots only
the calculated points of the selected functions.
Note: The DOT-THICK plotting mode on the TI-84 Plus CE is equivalent to the

THIN plotting mode resets all Y= line styles to a thin line connecting each point
calculated for the selected functions.
Note: Use THIN plotting mode for function graphing when looking at any
functions which asymptote to an axis.
DOT-THIN plotting mode resets all Y= line styles to a small dot and plots only
the calculated points of the selected functions.
Keyboard Basics 21
22 Keyboard Basics
SEQUENTIAL SIMUL
SEQUENTIAL graphing-order mode evaluates and plots one function
completely before the next function is evaluated and plotted.
SIMUL (simultaneous) graphing-order mode evaluates and plots all selected
functions for a single value of X and then evaluates and plots them for the next
value of X.
Note: Regardless of which graphing mode is selected, the calculator will
sequentially graph all stat plots before it graphs any functions.
REAL a+bi re^(qi)
REAL mode does not display complex results unless complex numbers are
entered as input.
Two complex modes display complex results.
• a+bi (rectangular complex mode) displays complex numbers in the form
a+bi. The TI-84 Plus CE supports the n/d fraction template.
• re^(qi) (polar complex mode) displays complex numbers in the form
re^(qi).
FULL HORIZONTAL GRAPH-TABLE
FULL screen mode uses the entire screen to display a graph or edit screen.
Each split-screen mode displays two screens simultaneously.
• HORIZONTAL mode displays the current graph on the top half of the
screen; it displays the home screen or an editor on the bottom half.
• GRAPH-TABLE mode displays the current graph on the left half of the
screen; it displays the table screen on the right half.

28 Evaluating Expressions
Evaluating Expressions
An expression is a group of
• numbers,
• variables,
• functions and their arguments,
-or-
• a combination of these elements.
An expression evaluates to a single answer.
On the TI-84PlusCE, you enter an expression in the same order as you would
write it on paper. For example: pR
2
is an expression.
Order of Operations
The TI-84 Plus CE uses an order of operations system called Equation
Operating System (EOS™), which
• defines the order in which functions in expressions are entered and
evaluated
-and-
• allows you to enter numbers and functions in a simple, straightforward
sequence.
EOS™ evaluates the functions in an expression in this order:
Order Function
1 Functions that precede the argument, such as sin( or log(
2 Functions that are entered after the argument, such as 2, -1, !, ¡, r,
and conversions
3
Powers and roots, such as 2
5
or
5 32
x
4 Permutations (nPr) and combinations (nCr)
5 Multiplication, implied multiplication, and division
Order Function
6 Addition and subtraction
7 Relational functions, such as > or
8 Logic operator and
9 Logic operators or and xor
Note: Within a priority level, EOS™ evaluates functions from left to right.
Calculations within parentheses are evaluated first. A number in scientific or
engineering notation, 2.34â6, is interpreted as (2.3x10
6
) with parentheses so
the number remains the correct value during the EOS™ calculation.
Implied Multiplication
The TI-84PlusCE recognizes implied multiplication, so you do not need to
press ¯ to express multiplication in all cases. For example, the TI-84PlusCE
interprets 2p, 4sin(46), 5(1+2), and (2 ä 5)7 as implied multiplication.
Note: TI-84PlusCE implied multiplication rules differ from those of some other
graphing calculators. For example, the TI-84PlusCE evaluates 1à2X as (1à2)
X, while some graphing calculators may evaluate 1à2X as 1à(2 X).
Parentheses
The TI-84 Plus CE completes all calculations inside a pair of parentheses first.
For example, in the expression 4(1+2), EOS™ first evaluates the portion inside
the parentheses, 1+2, and then multiplies the answer, 3, by 4.
Negation
To enter a negative number, use the negation key. Press k and then enter the
number. On the TI-84PlusCE, negation is in the third level in the EOS™
hierarchy. Functions in the first level, such as squaring, are evaluated before
negation.
Evaluating Expressions 29
30 Evaluating Expressions
Example: MX
2
, evaluates to a negative number (or 0). Use parentheses to
square a negative number.
Note: Use the j key for subtraction and the k key for negation. If you press j
to enter a negative number, as in 9 ¯ ¹ 7, or if you press k to indicate
subtraction, as in 9 k 7, an error occurs. If you press ƒ A k ƒ B, it is
interpreted as implied multiplication (A)(MB).
Entering Expressions and Instructions
You can use an expression on the home screen to calculate an answer. In
most places where a value is required, you can use an expression to enter a
value.
Entering an Expression
To create an expression, you enter numbers, variables, and functions using the
keyboard and menus. An expression is evaluated when you press Í,
regardless of the cursor location. The entire expression is evaluated according
to EOS™ rules, and the answer is displayed according to the mode setting for
Answer.
Note: Most TI-84PlusCE functions and operations are symbols comprising
several characters. You must enter the symbol from the keyboard or a menu;
do not spell it out. For example, to calculate the log of 45, you must press «
45. Do not enter the letters L, O, and G. If you enter LOG, the TI-84PlusCE
interprets the entry as implied multiplication of the variables L, O, and G.
To enter a matrix name:
1. Press y ¾.
The Matrix Names menu appears.
2. Press the number on the keypad that corresponds with the desired Matrix
Name.
Ex: Press 1 for [A] as shown.
Note: In MathPrint™ mode, press ~ to get out of the MathPrint™ template and
continue entering the expression.
Calculate 3.76 P (L7.9 +$ 5) + 2 log 45.
MathPrint™ Classic
3 Ë 76 ¥ £ k 7 Ë 9 Ã y C 5

Note: The ~ is a notable keystroke
difference as compared to Classic.
3 Ë 76 ¥ £ k 7 Ë 9 Ã y C 5 ¤ ¤
à 2 « 45 ¤ Í
Multiple Entries on a Line
To enter two or more expressions or instructions on a line, separate them with
colons (ƒ m). All instructions are stored together in last entry (ENTRY).
Evaluating Expressions 31
32 Evaluating Expressions
Entering a Number in Scientific Notation
1. Enter the part of the number that precedes the exponent. This value can be
an expression.
2. Press y D. â is pasted to the cursor location.
3. Enter the exponent, which can be one or two digits.
Notes:
• If the exponent is negative, press k, and then enter the exponent.
• â stands for "x10" and the calculator interprets the entire number as
(1.23.45 x 10
-2
) as if it was entered with parentheses.
When you enter a number in scientific notation, the TI-84PlusCE does not
automatically display answers in scientific or engineering notation. The mode
settings and the size of the number determine the display format.
Functions
A function returns a value. For example, log( and sin( are functions. In general,
the first letter of each function is lowercase. Most functions take at least one
argument, as indicated by an open parenthesis following the name. For
example, sin( requires one argument, sin (value).
Note: To see the arguments of a function or command in the calculator, find the
item in a menu or y N and press +. For most menu items, a Catalog
Help screen will display and the syntax of the arguments will be displayed.
Instructions
An instruction (command) initiates an action on the calculator. For example,
ClrDraw is an instruction to the calculator to clear drawn elements from a graph.
Instructions cannot be used in expressions. In general, the first letter of each
instruction name is uppercase. Some instructions take more than one
argument, as indicated by an open parenthesis at the end of the name. For
example, on the TI-84PlusCE, Circle( requires three arguments, and has two
optional arguments: Circle(X,Y,radius[,color, linestyle]).
Interrupting a Calculation
To interrupt a calculation or graph in progress, which is indicated by the busy
indicator in the status bar, press É.
When you interrupt a calculation, a menu is displayed.
• To return to the home screen, select 1:Quit.
• To go to the location of the interruption, select 2:Goto.
When you interrupt a graph, a partial graph is displayed.
• To return to the home screen, press ‘ or any non-graphing key.

stored in Flash archive, but they are used in different ways.
Working with Graphs 37
38 Working with Graphs
Using Pictures and Backgrounds
• Image Vars (Image1 - Image9, and Image0) are variables stored in archive
memory. An Image Var is used as a Background Image in the graph area.
Several images are pre-loaded on the TI-84PlusCE. You can also convert
images to TI-84 Plus CE Image Vars in the TIConnect™ CE software and
load them to the calculator. You cannot create images on the calculator.
Note: TIConnect™ CE software is available as a free download from
education.ti.com/go/download.
• Pic Vars (Pic1 - Pic 9, and Pic0) are also variables stored in archive
memory. Pic Vars can be created by drawing in the graphing area, and the
changes saved and recalled to the graphing area. Saving a Pic Var will not
include the Background Image behind your graphing area.
• Both Image Vars and Pic Vars are stored and run in Flash archive, not in
RAM. They are both accessible in the VARS menu.
• Image Vars and Pic Vars can only be shared with another TI-84PlusCE or
TI-84 C graphing calculator.
• TI-84 Plus Pic Vars cannot be shared between the TI-84 Plus and the TI-84
PlusCE graphing calculators.
• If you perform a RAM reset on the TI-84 PlusCE, the Image Vars and Pic
Vars remain in Archive memory for use.
Working with Matrices

Notes about Variables
• You can create as many list names as memory will allow.
• Programs have user-defined names and share memory with variables.
• From the home screen or from a program, you can store to matrices, lists,
strings, and system variables such as Xmax, TblStart, and all Y= functions.
• From an editor, you can store to matrices, lists, and Y=functions.
Working with Variables 47
48 Working with Variables
• From the home screen, a program, or an editor, you can store a value to a
matrix element or a list element.
• You can use DRAW STO menu items to store and recall Pic Vars.
• Although most variables can be archived, system variables including r, T,
X, Y, and q cannot be archived.
• Apps are independent applications, which are stored in Flash archive.
AppVars is a variable holder used to store variables created by
independent applications. You cannot edit or change variables in AppVars
unless you do so through the application that created them.
Storing Variable Values
Storing Values in a Variable
Values are stored to and recalled from memory using variable names. When
you evaluate an expression that contains a variable name, the graphing
calculator substitutes the value currently stored in that variable.
To store a value to a variable from the home screen or a program using the
¿ key, begin on a blank line and follow these steps.
1. Enter the value you want to store. The value can be an expression.
2. Press ¿.
! is copied to the cursor location.
3. Press ƒ and then the letter of the variable to which you want to store the
value.
4. Press Í. The graphing calculator evaluates the expression and stores
the value to the variable.
Displaying a Variable Value
To display the value of a variable, enter the variable name on a blank line on
the home screen, and then press Í.
Archiving Variables (Archive, Unarchive)
You can store variables in the TI-84PlusCE user data archive, a protected
area of memory separate from RAM. The user data archive lets you:
• Store data, programs, applications or any other variables to a safe location
where they cannot be edited or deleted inadvertently.
• Create additional free RAM by archiving variables.
By archiving variables that you do not need to edit frequently, you can free up
RAM for applications that may require additional memory.
The graphing calculator places an asterisk (ä)to the left of archived variables.
You cannot edit or execute archived variables. You can only see and
unarchive them.
Example:
If you archive a list named L1, you will see that it exists in memory. However, if
you select and paste the name L1 to the home screen, it will not appear on the
home screen. You must unarchive it in order to see its contents and edit it.
Note: Image Vars are run and stored in archive, but when an Image Vars
displays in VARS 4:Picture & Background, the BACKGROUND menu does not
display the asterisk ä.
Recalling Variable Values
