Calculation History and Replay

Calculation history maintains a record of each calculation you perform, including the
expressions you input and calculation results. You can use calculation history in the COMP,
CMPLX, and BASE Modes.

Accessing Calculation History

k

The ` symbol in the upper right corner of the display indicates that there is data stored in
calculation history. To view the data in calculation history, press f. Each press of f
will scroll upwards (back) one calculation, displaying both the calculation expression and its

result.

Example:

3+3

1+1w2+2w3+3

ff

2+2

6

E-13

w

While scrolling through calculation history records, the $ symbol will appear on the display,
which indicates that there are records below (newer than) the current one. When this
symbol is turned on, press c to scroll downwards (forward) through calculation history
records.

Important!

• Calculation history records are all cleared whenever you press p, when you change to a
different calculation mode, and whenever you perform any reset operation.

• Calculation history capacity is limited. Whenever you perform a new calculation while
calculation history is full, the oldest record in calculation history is deleted automatically to
make room for the new one.

Using Replay

Calculator Memory Operations

Using Answer Memory (Ans)

k

The result of any new calculation you perform on the calculator is stored automatically in
Answer Memory (Ans).

Ans Update and Delete Timing

A

When using Ans in a calculation, it is important to keep in mind how and when its contents
change. Note the following points.

• The contents of Ans are replaced whenever you perform any of the following operations:
calculate a calculation result, add a value to or subtract a value from independent
memory, assign a value to a variable or recall the value of a variable, or input statistical
data in the SD Mode or REG Mode.

• In the case of a calculation that produces more than one result (like coordinate
calculations), the value that appears first on the display is stored in Ans.

• The contents of Ans do not change if the current calculation produces an error.

E-14

• When you perform a complex number calculation in the CMPLX Mode, both the real part
and the imaginary part of the result are stored in Ans. Note, however, that the imaginary
part of the value is cleared if you change to another calculation mode.

Automatic Insertion of Ans in Consecutive Calculations

A

Example: To divide the result of 3 × 4 by 30

3*4

(Next)

Note

In the case of a function with parenthetical argument (page 8), Ans automatically becomes
the argument only in the case that you input the function alone and then press w.

Inserting Ans into a Calculation Manually

A

Example: To use the result of 123 + 456 in another calculation as shown below

123 + 456 = 579 789 – 579 = 210

Using Independent Memory

k

Independent memory (M) is used mainly for calculating cumulative totals.
If you can see the M symbol on the display, it means there is a non-zero value in
independent memory. Independent memory can be used in all calculation modes, except
for the SD Mode and the REG Mode.

M symbol

+

Adding to Independent Memory

A

While a value you input or the result of a calculation is on the display, press m to add it to
independent memory (M).

A

While a value you input or the result of a calculation is on the display, press
subtract it from independent memory (M).

Example: To subtract the result of 3 × 2 from independent memory (M)

3*2

Note

Pressing m or
subtract it from independent memory.

Important!

The value that appears on the display when you press m or
calculation in place of w is the result of the calculation (which is added to or subtracted
from independent memory). It is not the current contents of independent memory.

time before the calculation result appears. Do not perform any key operation on the
calculator until the calculation result appears.

• To interrupt and on-going calculation operation, press A.

Interpreting Scientific Function Syntax

• Text that represents a function’s argument is enclosed in braces ({ }). Arguments are
normally {value} or {expression}.

• When braces ({ }) are enclosed within parentheses, it means that input of everything
inside the parentheses is mandatory.

Pi (π) and Natural Logarithm Base

k

The calculator supports input of pi (π) and natural logarithm base e into calculations. π and

e

are supported in all modes, except for the BASE Mode. The following are the values that

the calculator applies for each of the built-in constants.

• These functions can be used in the CMPLX Mode, as long as a complex number is not
used in the argument. A calculation like

is not.

• The angle unit you need to use in a calculation is the one that is currently selected as the
default angle unit.

Angle Unit Conversion
