BASIC CALCULATIONS
Arithmetic Calculations
• To calculate the negative values (excludes the 
negative exponent), you have to enclose them with 
parentheses.
•  This Calculator supports 24-level of parenthetical  expression. 
•  You can omit the close parentheses        as the  calculation ends with        or        .  (Example #4)
!  When the number of        is more than       , [Syntax  ERROR] will be shown.
  Press                to enter COMP mode as you want to 
perform basic calculations. 
  During the busy calculation, the calculator will display  the message [PROCESSING]. 
Memory Calculations
Memory Variables (Example #5)
•  There are 17 memory variables (0 through 9, A through D, M, X, and Y) which store data, results, or dedicated 
values. 
•  To store values into memory by pressing        + Memory  variable. 
•  To recall memory values, press        + Memory variable.
•  Memory content can be cleared by simply pressing     
        + Memory variable.
Independent Memory (Example #6) 
•  Independent memory       uses the same memory area  as variable M. It is convenient for calculating cumulative 
total by just pressing
        (add to memory) or       (subtract from memory);  and the memory contents are retained even when the 
calculator is turned off. 
•  To clear independent memory (M), input  
•  When you want to clear all memory values, press                                          (Mcl)

numerator + denominator + separator marks) exceeds 10.
•  As a fraction calculation is mixed with decimal value, the  result will be displayed by decimal format.
