  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
Example 2:
   2    A
   1 ÷ 2A =

 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 
calculation result). Press        key to interrupt the 
calculating operation.

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) 
                   .

  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.
