HP Prime Getting Started Content (three topics) plus Arithmetic Fundamentals

Getting started consist of thee topics: Generalities, Settings, and Examples.

This page, Arithmetic Fundamentals, is new. The Arithmetic Fundamentals’ page and its fly-out pages are being added for 2022. The Arithmetic Fundamentals’ page and its fly-out pages rely on a holistic approach to learn how the HP Prime calculator can be used in arithmetic. This page and its fly-out pages are used to assist our new printed paperback HP Prime Guide THE SILVER-BURDETT ARITHMETICS (Annotated) Selected Exercises and OneNote’s Basic Math (HP Prime Guide Arithmetic Fundamentals) notebook in implementing this holistic approach to learning how the HP Prime calculator can be used in arithmetic.

The Keyboard in Getting Stated contains a wealth of information that you might want to look at.

To navigate the three Getting Started topics, you can use the links at the top of the page or the drop-down HP Prime menu. All the HP Prime menu pages have links to subtopics listed on the page. Use these links to go quickly to the subtopic area.

Arithmetic Fundamentals

 Arithmetic Fundamentals and its fly-outs covers our new 120-page paperback, HP Prime Guide THE SILVER-BURDETT ARITHMETICS (Annotated) Selected Exercises, and FREE OneNote hyper-linked notebook, Basic Math (HP Prime Guide Arithmetic Fundamentals). Either way you can get started with an introduction to the calculator features of the HP Prime.

The HP Prime instructions are identical in the paperback and notebook. The difference ls that the paperback has copies of Book Two of THE SILVER-BURDETT ARITHMETICS related exercises pages and their answer page(s) that follow each arithmetic topic but is unable to implement hyper-links while the live notebook has hyper-link resources for each topic but does not have the related exercises and answer pages for the topic.

The notebook does have in the Resources for Getting Started Section all the Google scans and Internet  Archive direct links for all the books in THE SILVER-BURDETT ARITHMETICS series.  You will have to search the scanned book for the related exercises and in Book One and Book Two search the back of the scanned book for the answers. Note that Google and Internet Archive scanned Book Three and Complete Book do not have scanned answer pages.

To see how the HP Prime calculator supports arithmetic click on Basic Math (HP Prime Guide Arithmetic Fundamentals to open the OneNote’s notebook. You may need to use OneNote’s Navigation Icon see all the text.

Remember, if you are looking for topic related additional practice exercises with answers for OneNote’s Basic Math (HP Prime Guide Arithmetic Fundamentals) notebook look at our 120-page HP Prime Guide THE SILVER-BURDETT ARITHMETICS (Annotated) Selected Exercises paperback book. Just select the exercises from that section topic that you want to work and with the extra practice turn your HP Prime calculator into a valuable resource and learning tool.

General Overview

If turning on for the first time, read our Initial Settings directions otherwise 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. As shown in the screen below we can do calculations using units. To add a unit press the [Units] key. If the value being labeled is complex enclose the value in a [( )].



Besides arithmetic calculations, we can use units and convert from one unit to another unit.  Shown is the Prime’s convert command, CONVERT. In the screen it  is shown being used twice. We prefer its abbreviated (alternate) form. It allows us to convert a measurement from one unit to another.  Pressing [Enter] twice allows us to display result in two forms. The [a b/c]  key toggles the form of the result. The first line had a parenthesis around the 1/2.

In the  tutorial we use the  CONVERT() screen to illustrate using [Help] for a command and clearing the command line by pressing [Esc]. By pressing [Clear] the History area is cleared. We use the [Esc]  [Clear] sequence of key strokes before beginning a new problem in order to erase the command line and History.



Shown in the screen are four Prime examples for addition and subtraction of fractions. The Prime represents a mixed numeral with a plus sign connecting the whole part and fraction part. It is necessary to use parenthesis to group the whole and fraction part of the subtrahend when subtracting it.

The danger with using the Prime to perform calculations is that for what looks like the correct problem entered in the command line will give the incorrect display and answer of 369/8 in the History area. It subtracted 25 from the first mixed numeral and then added 5/8 to that result rather then subtracting (25 + 5/8) for correct answer of 359/8. For clarity it is best to use parenthesis for both parts.
