This exercise shows you how to:
¦ Enter and format ordinary text.
¦ Access and use the Math Pa ette.
¦ Use a Math Box object to perform simp e ca cu ations in a
document.
¦ Enter math and other specia functions symbo s.
¦ Save a TI InterActive! document.
Exercise 1: Performing Calculations in a Document
You perform many calculations in TI InterActive!documents by
inserting a Math Box object. Data that you store and functions
that you define in a Math Box can be used by subsequent
objects, such as graphs, tables, and other Math Boxes.

Entering text in a TI InterActive! document is simi ar to entering
text in most text editors and word processors. For this exercise,
you enter a page tit e and then change the font and point size.
1. Type Homework on the first ine of your document.
2. High ight the typed text and se ect a different font type and
size from the font dia og box (Format 8 Font).
3. P ace the cursor at the end of the ine and press the Enter key
on the computer keyboard to start a new ine.
Suppose you want to eva uate an expression such as 28• 43

2. Type 2^8*43à12 into the Math Box. Press the Enter key on
the computer keyboard or c ick on the Math Pa ette to
eva uate the expression. TI InterActive! eva uates the
expression, disp ays the resu t, and creates another Math
Box.
3. Press the Esc key on the computer keyboard to c ose the
unused Math Box.
You might expect to see a decima resu t instead of 2752à3 in the
preceding examp e. A c ose decima equiva ent is 917.33333..., but
that’s on y an approximation. By defau t, TI InterActive! retains
the more precise form: 2752à3.
You can, however, change the form of any Math Box resu t by
setting the Computation Mode of the box.
1. C ick anywhere in the existing Math Box to se ect it. A so id
border appears around the Math Box to show that it is
se ected.
2. C ick the Mode Settings button on the TI InterActive!
too bar.
TIP: Make sure you

Note the three options avai ab e under Computation Mode:
Automatic Uses Exact where possib e, but uses
Approximate when your entry contains a
decima point. A so, certain functions may
disp ay Approximate resu ts even if your entry
does not contain a decima point.
Exact Any resu t that is not a who e number is
disp ayed in a fractiona or symbo ic form (1à2,
p, 2, etc.). This mode reduces rounding errors
that cou d be introduced by intermediate
resu ts in chained ca cu ations.
Approximate A numeric resu ts, where possib e, are
disp ayed in decima form.
3. C ick the Approximate option to se ect it, and c ick OK. The
resu t in the Math Box becomes a decima approximation.
4. C ick the Mode Settings button again, and change the
Computation Mode back to Automatic, the origina setting,
and c ick OK.
This chart compares the Computation Mode settings.

This exercise shows you how to:
¦ Define a variab e and assign a va ue to it.
¦ Disp ay a variab e’s va ue in a document.
¦ Remove a variab e.
¦ Perform symbo ic ca cu ations.
¦ Reposition TI InterActive! objects in a document.
¦ Reset a variab es.
Exercise 2: Storing Values as Variables
You can store a value as a named variable and then use the name
to refer to that value in subsequent Math Boxes and graphs. When
TI InterActive!evaluates an expression containing the name, it
substitutes the value stored under that name.

This examp e creates a variab e named num and stores the resu t
of the expression 5+83 in that variab e.
1. On the TI InterActive! too bar, c ick the New button to
start a new, b ank document.
2. C ick the Math Box button to insert a new Math Box.
3. Type the variab e name num and then type := (both
characters are required from the keyboard), or c ick on
the Math Pa ette.
num :=
4. Type the expression 5+8^3. The resu t—not the expression—
wi be stored in num.
num := 5+8^3
5. Press Enter on the computer keyboard. TI InterActive!
creates the variab e num and stores the resu t there.
You can check the va ue of a variab e by entering its name as the
entry in a subsequent Math Box.
1. C ick the Math Box button to insert a new Math Box, if
necessary.
2. Type the variab e name num and press Enter on the computer
keyboard. The va ue current y stored in num is disp ayed as
the resu t.
Storing a value
in a variable
TIP: If you have
changed a document
and then attempt to
create a new document,
TI InterActive! gives you
the option to save the
first document before
proceeding.
Checking a
variable’s value
This means: Let the variable “num”
equal the result of 5+83.

After storing a va ue in a variab e, you can use the variab e name
in an expression as a substitute for the stored va ue.
1. C ick the Math Box button to insert a new Math Box, if
necessary.
2. Type 4*25*num^2 in the Math Box, and press Enter.
TI InterActive! substitutes 517, the va ue assigned to num, and
eva uates the expression.
3. Type 4*25*nonum^2 in a Math Box, and press Enter.
Because the variab e nonum has not been defined, it is treated
a gebraica y in the resu t.
If you want to update a variab e with the resu t of a ca cu ation,
you must store the resu t exp icit y.
