Operations of the same precedence are performed from right to left.
For example: exln 120 ex{ln( 120)}. Other operations are
performed from left to right
Operations enclosed with parentheses are performed first. When a
calculation contains an argument that is a negative number, 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 error.
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 accordingly.
Error Message Cause 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 Calculations
Memory 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 +

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.
