How to do constant multiplication or division on the Canon P170-DH calculator

This process actually requires fewer keystrokes than other calculators. Basically, just do the first problem
and then do the next items with just the next number and the EQUAL key. For example,

*** Constant Multiplication ***
2 (multiply key)
10 (= key)
(The answer 20 shows on the screen. Note, the 2 is still stored as a constant without doing anything, just continue)
4 = (shows the answer 8 on the screen)
20 = (shows the answer 40 on the screen)
100 = (shows the answer 200 on the screen)

*** Constant Division ***
10 (divided by key)
2 =
(shows the answer 5 on the screen, the 2 is still stored as a constant without doing anything, just continue)
100 = (shows the answer 50 on the screen)
500 = (shows the answer 250 on the screen)
4 = (shows the answer 2 on the screen)
