Question about Canon P170-DH Calculator

Hi....by looking at the date you posted this question, you may have already found the answer, but just in case you haven't......the procedure for adding and subtracting on these calculators is completely opposite of a regular calculator. On a regular calculator, you would input 4 - 4 = 0. On these type of calculators, a number's positive or negative status is keyed in AFTER the number, instead of before it. Therefore, you input 4 + 4 - (notice you DO NOT input = at the end, but if you are in print mode, you will need to hit your total key, which looks like an asterisk, where the = would normally be, in order for the final value of your calculations to print on the paper tape.

Multiplication and division equations are done exactly as they are on a regular calculator....4 x 4 = 16.

Hope this helps. If you have your owners manual, it should also give you some examples of how to perform calculations with your calculator.

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)
