• Parentheses („Ü) can be used to group operations, as well as to
enclose arguments of functions.
In ALG mode:
„Ü5+3.2™/„Ü7-
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 single quotes will allow
you to enter the expression like in algebraic mode:
³„Ü5+3.2™/
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
• The absolute value function, ABS, is available through „Ê.
Example in ALG mode:
Example in RPN mode:
• The square function, SQ, is available through „º.
Example in ALG mode:
Example in RPN mode:
The square root function, , is available through the R key. When
calculating in the stack in ALG mode, enter the function before the
argument, e.g.,
In RPN mode, enter the number first, then the function, e.g.,
6.3#8.5-
