•Parentheses („Ü) can be used to group operations, as well as to enclose arguments of functions.

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 single 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@

•The absolute value function, ABS, is available through „Ê. Example in ALG mode:

„Ê\2.32`

Example in RPN mode:

2.32\„Ê

•The square function, SQ, is available through „º. Example in ALG mode:

„º\2.3`

Example in RPN mode:

2.3\„º

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.,

R123.4`

In RPN mode, enter the number first, then the function, e.g.,

123.4R
