Instructions

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.

HP Prime Onenote Break Even or direct link

We use functions c(x) and r(x) to help with implementing the solve command and plotting of functions on the HP Prime. Following the help screen comments, the command solve for simultaneous equations needs the equations inside a comma separated list using braces, with the variable inside brackets. When working in CAS view we us c(x) and r(x). When plotting the graph we use c(X) and r(X). The letters c and r are lower case in both cases. The letter x is lower case in CAS view and when using the Function app to plot a graph we use uppercase X as the paramenter for c and r.

Supply and Demand

The following video describes how to solve a break even word problem.

The video solve a specific supply and demand problem. It show a graph of the solution using HP Prime. HP Prime for windows 10 techniques are shown.

HP Prime Onenote Supply and Demand or direct link

We use functions d(x) and s(x) to help with implementing the solve command and plotting of functions on the HP Prime. The command solve for simultaneous equations needs the equations inside a comma separated list using braces, with the variable inside brackets. When working in CAS view we us d(x) and s(x). When plotting the graph we use d(X) and s(X). The letters c and r are lower case in both cases. The letter x is lower case in CAS view and when using the Function app to plot a graph we use uppercase X as the paramenter for d and s.

Use Onenote to add solution -200x + 1100 = 75x. Have digital Math Assistant solve for x and show the steps.
