• In the input table, up to 6 digits are displayed for each value,
including the sign and decimal point. Any values that exceed 6 digits
in length are displayed in exponent notation.
•
Up to 100 data items can be entered. With single-variable data,
a data item with an assigned frequency of one is counted as one
data item, while an item with an assigned frequency of 2 or higher
is stored as a set of two data items. With two-variable data, a set of
data items with an assigned frequency of one is counted as two data
items, while a set of items with an assigned frequency of 2 or higher
is stored as a set of three data items.
• To execute statistical calculation, press _ or jand close the
input table.
Data correction
Use l, r, u, or dto move the cursor and select the
desired data. Press @uor @dto jump the cursor to the
beginning or end of the data.

Statistical Calculations and Variables
The following statistics can be obtained for each statistical calculation
(refer to the table below):
Single-variable statistical calculation
Statistics of 1, 3and the value of the normal probability function.
Linear regression calculation
Statistics of 1, 2and 4. In addition, the estimate of y for a given x
(estimate
y ´) and the estimate of x for a given y (estimate x ´).
Quadratic regression calculation
Statistics of 1, 2and 4. And coefficients a , b , c in the quadratic
regression formula (
y = a + bx + cx
2
). (For quadratic regression
calculations, no correlation coefficient (
r ) can be obtained.)
When there are two
x ´ values, each value will be displayed with “1:” or
“2:”, and stored separately in the X and Y memories.
You can also specify the 1st value (x1’) and the 2nd value (x2’) separately.
Euler exponential regression, logarithmic regression,
power regression, inverse regression,
and general exponential regression calculations
Statistics of 1, 2and 4. In addition, the estimate of y for a given
x and the estimate of x for a given y . (Since the calculator converts
each formula into a linear regression formula before actual calculation
takes place, it obtains all statistics, except coefficients aand b, from
converted data rather than entered data.)

Ex. 2 +&5 =
ERROR 02: Calculation error
• The absolute value of an intermediate or final calculation result equals
or exceeds 10100.
• An attempt was made to divide by zero (or an intermediate calculation
resulted in zero).
• The calculation ranges were exceeded while performing calculations.
• 0 or a negative number was entered as a step value in TABLE mode.
The absolute value of a starting value or a step value equals or
exceeds 10100 in TABLE mode.
• When the number to be factored into primes is greater than 2 and
other than a 10-digit positive integer, or when the result of prime
factorization is a negative number, decimal, fraction, r,or π.
ERROR 03: Nesting error
• The available number of buffers was exceeded. (There are 10 buffers*

• Matrix/vector dimensions inconsistent while calculating.
ERROR 10: Undefined error
• Undefined matrix/vector used in calculation.
Alert Messages
Cannot delete!
• The selected item cannot be deleted by pressing Nor @y
in the WriteView editor.
Ex. *5 rAlN
In this example, delete the exponent before attempting to delete the
parentheses.
Cannot call!
• The function or operation stored in definable memory (D1 to D3)
cannot be called.
Ex. An attempt was made to recall a statistical variable from within
NORMAL mode.
Buffer full!
• The equation (including any calculation ending instructions) exceeded
its maximum input buffer (159 characters in the WriteView editor or
161 characters in the Line editor). An equation may not exceed its
maximum input buffer.
Calculation Ranges 36
• Within the ranges specified, this calculator is accurate to ±1
of the 10th digit of the mantissa. However, a calculation error
increases in continuous calculations due to accumulation of each
calculation error. (This is the same for yx, xr, n!, ex, ln, Matrix/
Vector calculations, Π, etc., where continuous calculations are
performed internally.)
Additionally, a calculation error will accumulate and become
larger in the vicinity of inflection points and singular points of
functions.
• Calculation ranges
±10−99 to ±9.999999999 ×1099 and 0.
If the absolute value of an entry or a final or intermediate result of
a calculation is less than 10−99, the value is considered to be 0 in
calculations and in the display.
Display of results using r(when EXACT is selected)
Calculation results may be displayed using rwhen all of the following
conditions are met:
• When intermediate and final calculation results are displayed in the
following form:
±aP
b

e± cP
d

f
• When each coefficient falls into the following ranges:
1 ≤a <100; 1 <b <1,000; 0 ≤c <100;
1 ≤d <1,000; 1 ≤e <100; 1 ≤f <100
• When the number of terms in the intermediate and final calculation
results is one or two.
Note: The result of two fractional terms that include rwill be reduced to
a common denominator.
BATTERY REPLACEMENT
Notes on Battery Replacement
Improper handling of batteries can cause electrolyte leakage or explosion.
Be sure to observe the following handling rules:
• Make sure the new battery is the correct type.
• When installing, orient the battery properly as indicated in the
calculator.
• The battery is factory-installed before shipment, and may be exhausted
before it reaches the service life stated in the specifications.
Notes on erasure of memory contents
When the battery is replaced, the memory contents are erased.
Erasure can also occur if the calculator is defective or when it is
repaired. Make a note of all important memory contents in case
accidental erasure occurs.
When to Replace the Battery

remove the battery, reinstall it, and check the
display once again.
Modifying a stored matrix
1. To load a stored matrix into the matrix entry screen, press N
2, then select the memory (matA–matD) that you wish to
modify.
• Loading new data into the screen will automatically replace any
data that may already exist there.
2. Modify the values of elements in the matrix, and press eafter
each one.
• If you wish to modify the number of rows or columns, first press
jN1. You can then enter new values for the matrix
dimensions.
3. When you have finished making changes, press jto exit the
matrix entry screen.
4. Press N3and select a memory (matA–matD) to store the
newly-created matrix in.
Using Matrices in Calculations
Matrices stored in memories (matA–matD) can be used in arithmetic
calculations (with the exception of division between matrices) and
calculations that use x3, x2, and x−1. You can also use the following
matrix-specific functions that are available in the MATH menu.
det matrix name Returns the determinant of a
square matrix.
trans matrix name
Returns the matrix with the
columns transposed to rows and
the rows transposed to columns.
identity value
Returns the identity matrix with
specified value of rows and columns.
dim (matrix name, row, column) Returns a matrix with dimensions
changed as specified.
fill (value, row, column) Fills each element with a specified
value.
rand_mat (row, column)
Returns a random matrix with
specified values of rows and columns.
ref(matrix name) Transform to row echelon form.
rref(matrix name) Transform to reduced row echelon
form.
Notes:
• When the matrix entry screen is displayed, you cannot perform
matrix calculations because the MATH menu is not available.
• If the calculation result is a matrix, it will be displayed in the matrix
entry screen (note that this replaces any existing data in the buffer).
To store the calculation result, first press jto exit the matrix
entry screen. Press N3and select a memory (matA–matD)
to store the newly-created matrix in.
• When the calculation results are in matrix form, pressing neither
lnor rwill bring you back to the original expression.
VECTOR CALCULATIONS 35
You can store and calculate up to four vectors of two or three
dimension in VECTOR mode.
Entering and Storing Vectors
Before performing vector calculations, a vector must be created.
Follow the steps below to enter and store vectors.
1. Press b6to enter VECTOR mode.
2. Press N1to bring up the vector entry screen.
•
Any vector data remaining in the buffer, along with any previously
entered, loaded, or calculated vector data, will be displayed.
3. Define the vector dimensions (2 dimensions or 3 dimensions) by
using the number keys and pressing e.
4. Enter each element in the vector by entering a value in the entry
field and pressing e.
• Each vector element can display up to seven digits (the decimal
point counts as one digit).
If an element exceeds seven digits in length, it may be displayed
in exponent notation within the vector.
5. When you have finished entering a value for each element, press
jto exit the vector entry screen.
6. Press N3and select a memory (vectA–vectD) to store the
newly-created vector in.
Modifying a stored vector
