Special Keys

[ ( ], [ ) ] Parenthesis Keys
This calculator uses true algebraic logic. It performs calculations using
the following priority:
1) Functions
2) Calculations in parenthesis
3) Power and root calculations
4) Multiplication and division
5) Addition and subtraction
To change this order, enclose the expressions that must be calculated
first within [ ( ] and [ ) ]. In a single expression, you can use a
maximum of 42 nested parentheses at 6 levels (nesting of up to 7
parentheses in one level).
For example, if you press [−] 6 [x
−36. This might seem incorrect at first, since the square of a negative
number is always positive. However, if you refer to the above priority
sequence, you see that the power ([x
minus ([−]). So the calculator sees the entry as "the negative of six
squared." To make the calculator perform "negative six, squared"
enter [ ( ] [−] 6 [ ) ] [x
6 and then square the result.
