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....
