Next, we look at using the HP Prime for this page. The HP Prime Lite / Free works as well.

Using the HP Prime

We will use four screen collage approach to explain our HP Prime solutions. The four screen collage allows us to have multiple problems shown in a small area using Textbook display. Press the HOME key to change to HOME view. Use the Clear key to erase any previous work.

The upper left screen, figure 2, shows us selecting the COMB function. Press the Toolbox key, then 5 and 2.

In the upper right screen, figure 2,  shows the results of multiplying two fractions and using the COMB function. The fraction answer was gotten by using the a b/c key. The second and fourth scientific notation answers are the default.

The lower left screen, figure 2, shows us pressing theCAS key. For the scientific answers we use the approx key. The default answer is fractions.

The lower right screen, figure 2, shows us working the second part of the problem using the HOME screen.
