Shown on this page are youtube videos using a digital pen on virtual paper assisted by a HP Prime calculator emulator. The content found here extends the content found in our eBook or print copy of HP Prime Guide Algebra Fundamentals.

Click on play and the full screen option in the Embedded youtube video or click on the direct link to go directly to the youtube site to play the video.

Embedded youtube video displays a dialog window when we hit pause. Do not hit the “X’ to close the dialog window, just press the play icon or space bar to resume play as it closes the dialog window and resumes play.

Remark: Onenote Ink math assistant requires a 365 subscription. There is the personal 365 subscription,  academic 365 subscription with Class Notebooks for administrators, teachers, and students plus organizational versions of 365 subscriptions that include Onenote Ink math assistant. The videos were made using the academic 365 subscription. You will need a 365 subscription to duplicate the Onenote Ink math assistant parts, however there are free versions of Onenote for all platforms that include Ink but not the Ink math assistant. There is an Online Onenote broswer version available with the Onenote Ink math assistant for some subscription packages


Tools

The video discusses the tools available to solve system of linear equations.  Go to 1:08 if you have pivmat loaded. We explore using the Math features of the HP Prime Calculator.

Microsoft is in the process of adding equation editor to 365 subscription of Onenote for Windows 10. They recommend you use equation editor in Word and copy and paste into Onenote for Windows 10. That is what we did to get the math expressions. We said returning to our Toolbox when we meant Tools page

Click link for instructions and video on how to use HP Connectivity Kit to load functions such as pivmat into a physical calculator. Pivmat allows us to verify manual row solutions of a matrix a column at a time. Pivmat is used to move from nonfeasible Linear Programing solutions to feasible solutions where built-in simplex_reduce function can be used to produce the optimal solution..


Higher Equations Higher Unknowns

The video solves system of linear equations, 5 equations, 5 unknowns with an infinite solution.  Go to 1:08 if you have pivmat loaded. We explore using the Math features of the HP Prime Calculator.
