Working in Algebraic Mode from RPN Mode

23. Let's now work the previous problem in Algebraic mode. You can actually use Algebraic mode with RPN set as the active operating
mode. Press the Tick key,
indicating Algebraic mode is now active. As an exercise, try to repeat the last example by typing the entire expression in as a
single equation.

25. Press
followed by ENTER(->NUM) to return the same numerical result, 4.5727... There are 66 keystrokes in Algebraic mode

compared to 61 with the RPN solution. However, you may have added some keystrokes with editing in order to get all the
parentheses in their correct locations. While RPN generally requires fewer keystrokes, having the ability to break problems into
smaller pieces helps you catch mistakes early on and avoid long, consecutive key sequences.
