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 =
1
4
Calculation Stacks
This calculator uses memory areas, called “stacks”, to
temporarily store numeric value (numbers) commands (+, –,
x…) and functions according to their precedence during
calculations.
The numeric stack has 10 levels and the command stack has
128 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.
