Using parentheses
Parentheses can be used to group operations, as well as to enclose arguments
of functions. The parentheses are available through the keystroke
combination
„Ü
. Parentheses are always entered in pairs. For
example, to calculate (5+3.2)/(7-2.2):
In ALG mode:
„Ü5+3.2™/„Ü7-2.2`
In RPN mode, you do not need the parenthesis, calculation is done directly on
the stack:
5`3.2`+7`2.2`-/
In RPN mode, typing the expression between quotes will allow you to enter
the expression like in algebraic mode:
³„Ü5+3.2™/
„Ü7-2.2`µ
For both, ALG and RPN modes, using the Equation Writer:
‚O5+3.2™/7-2.2
The expression can be evaluated within the Equation writer, by using:
————
@EVAL@
or,

@EVAL@
Absolute value function
The absolute value function, ABS, is available through the keystroke
combination:
„Ê
. When calculating in the stack in ALG mode, enter
the function before the argument, e.g.,
„Ê \2.32`
In RPN mode, enter the number first, then the function, e.g.,
2.32\„Ê
