Operations of the same precedence are performed from right to left. 
For example: e

performed from left to right
Operations enclosed with parentheses are performed first. When a 
calculation contains an argument that is a negative numbe r, the 
negative number must be enclosed within parentheses. 
Example:  (-2)
4 = 16; and -24 = -16

							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 stack 
values will be released.
Error Messages and Error Locator
The calculator is locked up while an error message is shown on the 
display to indicate the cause of the erro r. 
  Press        will clear the error , remove all replay memory and 
return to initial display of the latest mode.
  Press        will clear the error message and return to the display of 
the latest mode.
  Press      or      to display the calculation with the cursor 
positioned under the error and you can correct it accordingl y.
E rro r Messag eCause Action
Math ERROR  Calculation 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 your input values 
and make sure they are all 
within the allowable ranges. 
Pay special attention to 
values in any memory areas 
you are using.
Stack ERROR
The capacity of the numeric 
stack or operator stack is 
exceeded. Simplify the calculation.
 The 
numeric stack has 10 levels 
and the operator stack has 
24 levels.
Divide your calculation into 
two or more separate parts.

							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
Independent Memory 
   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

Result will be displayed in decimal format automatically whenever 
the total digits of a fractional value (integer + numerator + 
denominator + separator marks) exceeds 10.
  As a fraction calculation is mixed with decimal value, the result will 
be displayed by decimal format.

							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 is 12.5%, 85 is 42.5%, 90 is 45%
*  You can store the sum of value into memory variables, then recall 
and use the value by pressing        or        + Memory variable.

							Fix, Sci, Norm, ROUNDYou can change the number of decimal point, the number of 
significant digits, or the exponential notation criteria by pressing
                 to the following selection screen: 
Press 1 (Fixed Decimal Setting) :  [ Fix 0 ~ 9? ] appears, specify 
the number of decimal places 
by pressing        ~       .
Press 2 (Scientific Notation)  : [ Sci 0 ~ 9? ] appears, specify 
the number of significant digits 
by pressing        ~       .
Press 3 (Exponential Notation)  :  [ Norm 1 ~ 2? ] appears. 
Specify the exponential 
notation format by pressing        
or        . 
Norm 1 :  Exponential notation is automatically used for integer 
values with more than 10 digits and decimal values 
with more than two decimal point.
Norm 2 :  Exponential notation is automatically used for integer 
values with more than 10 digits and decimal values 
with more than nine decimal point.
