Basic Math Functions
The calculator displays results and accepts input of numbers up to a length of 11 characters. If a result
is longer than 11 digits, the calculator displays it in exponential notation. You can tap on the
key to
toggle between positive and negative numbers.
Using Basic Math Operators
Basic math operators function like a typical desk calculator. Tap a number, an operator, another
number, and an equal sign to see the answer displayed.
If you tap the equal sign directly after the operator, the calculator performs the operation on the initial
number that you tapped.
Example: Tap ‘6 x =’. The displayed result is 36.
If you tap more than one operator in a row, only the last operator is kept.
Example: Tap ‘6 x + 4 =’. The result is 10. The ‘+’ replaces the ‘x’.
If you tap the equal sign repeatedly in succession, it will repeat the previous calculation.
Example: Tap ’3 + 4 = =’ The initial result is 7. Then, 4 is added to 7 equaling 11.
Using Parentheses in Expressions
Normally the calculator respects the standard order of operations in an extended expression. However,
you can use parentheses in an expression to control the sequence of execution. You can nest
parentheses in order to further control of the calculation sequence. Each time you tap a close
parenthesis, the calculator calculates and displays the result of the enclosed expression.
