 Inputting and Display Result  in Mathematics Mode
  
In Mathematic Mode, the input and display result of 
fraction or certain functions (log, x
2, x3, x ,     , 3    ,     , x-1, 
10 , e , Abs) is shown in Handwriting/Mathematics 
format.
NOTE (1)  Some input expressions cause the height of a  calculation expression to be greater than one display 
screen. Maximum input capacity: 2 display screens 
  (31 dots x 2).
(2)  Calculator memory limits how many functions or  parentheses can be input in any single expression. In 
this case, divide the expression into multiple parts 
and calculate separately.
(3)  If part of the expression you input is cut off after  calculation and in the result display screen, you can 
press      or      to view the full expression.

  In the same precedence level, calculations are performed from left to right.
  Operations enclosed within parentheses are performed first.  When a calculation contains an argument that is a negative 
number, the negative number must be enclosed within the 
parentheses.
Example:
                            –2
2 = –4
                            (–2)2 = 4
  When same priority commands are mixed into one  calculation:
Example 1:
      1 ÷ 2    = 0.1591549431

 Calculation Stacks 
This calculator uses memory areas, called “stacks”, to 
temporarily store numeric value (numbers) commands (+, –, 
x…) and functions according to their precedence during 
calculations.
The numeric stack has 10 levels and the command stack has 
128 levels. A stack error [Stack ERROR] occurs whenever 
you try to perform a calculation that exceeds the capacity of 
stacks.
Calculations are performed in sequence according to “Order 
of Operations”. After the calculation is performed, the stored 
stack values will be released.
 Error Messages and Error Locator 
The calculator is locked up when an error message is shown on 
the display indicating the cause of the error.
  Press         to clear the error message, then return to the 
initial display of the latest mode.
  Press       or       to display the input expression with the  cursor positioned next to the error.
  Press         to clear the error message, replay memory history  and return to the initial display of the latest mode.

Error MessageCause ActionMath ERROR•  The intermediate or final 
result is outside the 
allowable calculation range.
•  An attempt to perform a  calculation using a value 
that exceeds the allowable 
input range.
•  An attempt to perform an  illogical operation (division 
by zero, etc.) • Check the input values and 
make sure they are all 
within the allowable 
ranges, Pay special 
attention to values in any

 Arithmetic Calculations 
•  To calculate the negative values (exclude the negative exponent) enclose then within the parentheses.
•  This calculator supports 99 levels of parenthetical  expression.
  Press                to enter COMP mode.
  As the calculation is busy processing, the calculator 
shows the message [PROCESSING] (without any

 Memory Calculations 
 Memory Variables
•  There are 19 memory variables (0 – 9, A – F, M, X and 
Y), which store data, results, or dedicated values.
•  Store values into memory by pressing              + Memory  variable.
•  Recall memory values by pressing        + Memory  variable.
•  Memory content can be cleared by pressing    
  + Memory variable.

Independent Memory
•  Independent memory       uses the same memory area as variable M. It is convenient for calculating cumulative 
totals by pressing        (add to memory) or      (subtract 
from memory).
•  Memory contents are retained even when the calculator  is powered off.
•  Clear independent memory (M) by pressing             
•  Clear all memory values by pressing                2(MCL) 
                   .
Answer Memory
•  The input values or the most recent calculation result will  be automatically stored into Answer memory whenever 
you press       ,              ,       ,             ,             . Answer 
memory can hold up to 18 digits.
•  Recall and use the latest stored Answer memory by  pressing        .
•  Answer memory is not updated when an error operation  has been performed.
•  Answer memory contents can be maintained even after  pressing       , changing the calculation mode, or turning 
off the calculator.

  Press         to switch a calculation result between fraction and decimal format.  Press                to switch a calculation result between improper fraction and mixed fraction format.  Results will be displayed in decimal format automatically whenever the total digits of a fractional value (integer + 
numerator + denominator + separator marks) exceeds 10. 
  When a fraction calculation is mixed with decimal values, the  result will be displayed in decimal format.

 Fraction Calculations 
The calculator supports Fraction calculation and the 
conversions between Fraction, Decimal point, Mixed fraction 
and Improper fraction.
•  Specify the fraction calculation result display format by 
selecting either mixed fraction (      ) or improper fraction
  (     ) in set-up menu.
•  At the default setting, fractions are displayed as improper  fractions (     ).
•  Mixed Fraction display results are only available after  
  selecting (      ) in the setup menu.
