exponential notation. You can tap on the key to toggle between positive and negative
numbers.
Using basic 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 equalling 11.
Using CE/C
Tap the key once to clear the current entry Tap it twice in a row to clear an entire
expression, including any pending operator. The key does not clear values in memory.
Using Parentheses
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.
Parentheses can be nested in order to further control of the calculation sequence. Each time a
close parenthesis is entered, the result of the enclosed expression is calculated and displayed.
Using Memory
You can store numbers in the memory register. When a value is present in memory an ‘M’
indicator appears. When the value in the memory changes, the indicator on your Pulse smartpen
display will blink. When the value in memory is zero, the memory indicator disappears.
Adds the currently displayed value to the value in the memory register.
Subtracts the currently displayed value from the value in the memory register.
