This worksheet contains examples of the functions
of the Advanced Keys.
The following instructions describe how to create
these entries in a new worksheet.
Tap the menu View/Advanced Keys to open the Advanced
Keypad.
Advanced operators can act directly on the current
total, or can act in combination with an entered
value and an Arithmetic operator (such as +, -, X,
/).
SQUARE ROOT
To compute the Square Root of a total, first enter
some values to create a total.
Tap the number buttons 1 0 on the calculator then tap
the + button. Repeat this for entries 2 0 + and so
on.
10 +
20 +
30 +
40 +
Tap the EQUAL (=) button to display the total in the
worksheet.
100 =
Tap the Sqrt button to compute the square root of
the current total. The result is is displayed in
the worksheet.
In this example, Sqrt operates directly on the
total.
10 Sqrt
Tap the CLEAR (C) button to clear the current total.

SQUARE
ROOT OF A
VALUE
ADDED TO
THE TOTAL
To compute the square root of an entered value and add
it to the current total, first tap the number
buttons 1 0 0 then tap the + button.
100 +
The current total is now 100
We'll compute the square root of 49. First tap the +
button. Tap the number buttons 4 9
Note that we did not tap the Sqrt button first. If
we had, it would have taken the Sqrt of the total.
This is an example of a "combined
Arithmetic/Advanced operation".
The Arithmetic Operator is set first, followed by a
number.
The + operator is set first because if we had tapped in
the number 4 9 followed by +, it would appear that we
want to ADD 49 to the total.
So, next tap the Sqrt button to complete the
entry.
Sqrt(49) +
Tap the = button to display the total in the worksheet.
107 =
Remember, for combined operations the sequence is
almost as you would "say":
"PLUS 49's SQUARE ROOT" or Arithmetic Operator, Value,
Advanced Operator.
Tap the CLEAR (C) button to clear the total.
0 C
TRIG
FUNCTION
Next we'll compute the height of a building given
a known distance and angle.
Assume the angle to the top of a building is 60 degrees
as seen by an observer on the ground.
Tap the number buttons 6 0 followed by the + button.
60 +
Tap the RADIANS (Rad) button to convert the angle
in degrees to radians.
1.0471975511966 Rad
All trig operators require a value in radians -- not
degrees.
Tap the Tan button to compute the tangent of the
angle.
1.73205080756888 Tan
Let's say that the distance in feet from observer to
the base of the building is 100 feet. Tap the number
buttons 1 0 0 then tap the X button.
100 X
Tap the = button to display the result, which is the
height of the building in feet
173.205080756888 =
Tap the ROUND button to round the total to whole
feet.
173 R
Tap the CLEAR (C) button to clear the total.

Nth ROOT
OF A
NUMBER
To compute the Nth root of a number, let's start with
a number known to be a certain power of 2. The
number 65536 is 2 to the 16th power.
Tap the number buttons 6 5 5 3 6 then tap the + button
to create a total of 65536.
65,536 +
Tap the Ln button to compute the natural log of
the total.
11.0903548889591 Ln
Tap the number buttons 1 6 then tap the DIVIDE (/)
button to divide the log by 16
16 /
Tap the "e^n" button to compute the antilog of the
total.
2 e^n
Tap the Text Entry Box to select it and type "The
16th root of 65536" on the Software Input Panel (SIP).
Do NOT type the asterisk. It will be assigned below
when this result is Used. Tap the = button to display
the result.
2 = The 16th root of 65536*
Tap the CLEAR (C) button to clear the total.
0 C
NUMBER TO
A POWER
Tap the row above containing the = operator,
labeled "The 16th root of 65536" to select it.
Next tap the Use button to select that row for "Use"
in the current entry. Next tap the + button to
complete the entry.
The asterisk on the left of the text indicates this row
Using another row's value.
2 + *The 16th root of 65536
To raise this number to the 16th power, tap the number
button 1 6 then tap the Pwr button.
16 Pwr
Tap the = button to display the result.
This result should be the same as the the value we
started with in the section "Nth ROOT OF A NUMBER".
65,536 =
Tap the CLEAR (C) button to clear the total.
0 C
Nth POWER
OF A
NUMBER
Tap the row labeled "The 16th root of 65536" above
to select it. Tap the + button.
2 + *The 16th root of 65536
Tap the number buttons 1 6 then tap the Pwr button.
16 Pwr
Tap the = button to display the result, which
is the number 2 raised to the 16th power.
It should be the same value as the number we started
with in the Nth ROOT OF A NUMBER section.
65,536 =
Tap the CLEAR (C) button to clear the total.

AREA OF A
CIRCLE
Next we'll compute the area of a circle having a radius
of 5 feet.
Tap the PI button to get the value of PI then tap
the + button.
3.14159265358979 +
Tap the number button 5 then tap the SQUARE (Sq)
button. Next tap the MULTIPLY (X) button.
Sq(5) X
Note that we used SQUARE (Sq) in a combined
Arithmetic/Advanced operation.
Remember the sequence is almost as you would "say"
it: "TIMES Five SQUARED".
Tap the = button to display the result, which is the
area of the circle.
78.5398163397447 =
Too many decimals?
Here's a way to round the result to 2 decimal places
without setting the global worksheet decimal places
option:
Multiply the result by 100 (or by 1000 for 3 decimal
places, and so on). Tap the ROUND (Round) button to
round the result. Divide by 100 (or 1000 for 3 decimal
places).

EXPONENTIAL
NOTATION
Next we'll compute the number of molecules in a
sample of carbon dioxide using Avogadro's Number.
The CO2 sample mass in grams is 13.2
Tap the number buttons 1 3 . 2 then tap the + button.
13.2 +
The molecular weight of CO2 is 44
Tap the number buttons 44 then tap the / button.
44 /
Next we'll enter Avogadro's number. Tap the Text Entry
Box and type "Avogadro's number" on the SIP.
First, we'll enter the exponent part of Avogadro's
Number. Tap the EXP (Exp) button on the Advanced
Keypad.
The exponent should be visible and the default
value ("000") should be underlined, indicating
numbers will be directed to the exponent.
Tap the number buttons 2 3.
The exponent should now be "E+23"
Tap the EXP button again to turn off exponent entry.
The exponent's underline should disappear. Numbers
will now be directed to normal number entry.
Next tap the number buttons 6 . 0 2 2 5 7 then
tap the MULTIPLY (X) button.
6.02257E+23 X Avogadro's Number
Tap the Text Entry Box and type "Molecules of CO2" on
the SIP. Tap the = button to display the result.
1.806771E+023 = Molecules of CO2
NOTE The exponent also can be
turned on/off by tapping the Number Entry Area,
directly above the Text Entry Box, except while in
Edit. In Edit, the EXP (Exp) button must be used.
The sign of the exponent can be changed by tapping
the "E" part of the exponent, OR by tapping the
TOGGLE SIGN (±) button above the Edit button when
the exponent is underlined.
HOW TO
MAKE
RESULTS
DISPLAY IN
EXPONENTIAL
FORM
The result of a EQUAL (=) operation is displayed as
exponential format if the exponent (E+000) is visible
in the Number Entry Area when you tap the = button.
If the exponent is not visible, the result will
displayed in ordinary numeric form.
However, in the case of a very large or small number,
the result will be displayed with the
exponent.
Also, the result displayed in the calculator Current
Result Area will be displayed in exponential
form if the last entry was in exponential form.
