This example creates a variable named
num
and stores the result
of the expression 5+8
3
in that variable.
1. On the TI InterActive! toolbar, click the New button
to
start a new, blank document.
2. Click the Math Box button
to insert a new Math Box.
3. Type the variable name
num
and then type
:=
(both
characters are required from the keyboard), or click
on
the Math Palette.
num
:=
4. Type the expression
5+8^3
. The result—not the expression—
will be stored in
num
.
num := 5+8^3
5. Press Enter on the computer keyboard. TI InterActive!
creates the variable
num
and stores the result there.
You can check the value of a variable by entering its name as the
entry in a subsequent Math Box.
1. Click the Math Box button
to insert a new Math Box, if
necessary.
2. Type the variable name
num
and press Enter on the computer
keyboard. The value currently stored in
num
is displayed as
the result.
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+8
3
.
