Calculation Stacks
 This calculator uses memory areas, called stacks, to temporarily 
store numeric value (numbers) and commands (+    x ...) 
according to their precedence during calculations.
  The numeric stack has 10 levels and the command stack has 24 
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...

Memory CalculationsMemory Variables
   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.
Example:  23 + 7 (Store to  A), calculate sin (memory  A), and clear 
memory  A

Degree-Minutes-Seconds Calculations
You can use degrees (hours), minutes and seconds key to perform a 
sexagesimal (base-60 notational system) calculation or convert the 
sexagesimal value into decimal value.
Degree-Minutes-Seconds         Decimal points Percentage Proportion : 
  the ratio/ percentage of each individual portion in 
a calculation expression. 
  If  A + B + C = D 
  A is a% of D where a =     x 100%
Examples:  To calculate the ratio of each portion as 25+85+90=200 
(100%), the ratio of 25...
