HP Prime Whole Numbers

To see how the HP Prime implements whole numbers calculations click on Basic Math to open the OneNote’s notebook. Select the Whole Number entry.

Press the [On] key to startup our HP Prime calculator. If in CAS view, press the [Home] key to change to Home view. Use the [Clear] key to erase any previous work. In the Generalities section we stated that a [Blue] key names require the [Shift] key first and [Orange] key names require the [ALPHA] key first. That pressing the [Shift] or [ALPHA] keys first is understood when a [Blue] or [Orange] name is used.

All keys will appear in [ ]s. Bold Black notation will be used for Black keys, White keys with Black lettering, and Black soft-key in the display. Numbers will be shown in plain text to make reading of their input easier. To add a unit press the [Units] key. If the value being labeled is complex enclose the value in a [( )].
