The multiplication key isn'yworking, can this be fixed?

Try taking some WD40 and spray the entire keyboard while pressing the buttons and then clean it up and try it again.

TI calculators have an annoying habit of dimming the screen when the batteries are changed so that it appears as if the calculator isn't turning on. Turn the calculator on (or at least press the ON key). Press and release the 2ND key. Press and hold the Up-arrow key for a few seconds and see whether the screen becomes legible.

There isn't one. Instead, the power key is marked "x-superscript-y" and is the second key from the right on the third row from the top, just above the red "C" key. Use this key whenever you'd use the "^" key on another calculator.

The one-over-x key is located two rows above the 7 key. The pi key is located just to the left of that.

First of all, the "1/x" key isn't the fraction key, it's "1-over-x." Pressing 3 1/x divides 1 by 3, giving you 0.33333333 .

If you want to enter a fraction, use either "a b/c" or "d/c," located just to the left of the 1 key. You can convert between decimal and fraction with "F--D" just below that.

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

This process actually requires fewer keystrokes than most 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)

--------------

Also note! There is no K visible on the screen to indicate a constant is set.
