Your calculator is fine. It is an adding machine first, so it uses adding machine logic and you hit the star button to print the total on the tape. The equals sign is only used when multiplying and dividing.

Adding machine logic is as follows:

5+ total 5

3- total 2

7+ total 9

* print out total

Good luck,

Paul

The manual for the Canon P1-DHV is online at http://www.usa.canon.com/app/pdf/calculator/P1-DHV_G_USA_HWB.pdf>.

When the display shows "5/4", the calculator is doing 5/4 rounding which means: 5 or above round up, 4 or below round down. To control rounding press the "5/4" key.

When the display shows "E" the calculator could not complete a calculation. It can be because of dividing by 0, or because the total exceeded 1 trillion, or because the operator entered calculations faster than the calculator could complete them. Press the CI/C key to clear it.

I can't explain why you are not getting a total on the tape. Try the following example from the manual exactly as shown, and let me know if your tape shows the total.

If your calculator is more of an adding machine it works a little bit differently than a calculator. For an example: 10 + 5 - 2 on your machine do the addition of 10 + 5, then to subtract the 2 press 2 then the minus sign to get the total of 13. I hope this is helpful.

Make sure you press the ENTER key after each data entry, before pressing the down-arrow key.

Hi,

MR is Memory Recall

MC is Memory Clear

M+ is Memory add

M- is Memory subtract

These are used to add and subtract the answers to multi-step equations so you can do the small steps with the calculator, then store, change or recall the total as needed. You might add a long string of numbers in groups this way. Or you can do all operations in one parenthesis, then just store the total of each.

A good problem to illustrate this would be : (123 x 3) + (55 - 24) + (10^2) - (7 x 8) = ???

Using MR, M+ and M-, you can do each one as a group, and only store the answers. 123 x 3 = 369 so M+ to put 369 in memory. Clear it from the calculator. 55 - 24 = 31, so M+ to put this in memory and add to the 369 already there. Clear it from the calculator. 10^2 = 100, so M+ this to memory also to add it. Clear it from the calculator. 7 x 8 = 56 so M- this to SUBTRACT it from memory. Clear it from the calculator if desired. Now, when you then hit MR, you will get the total of all of these small equations in parenthesis -- 444.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

M* = Memory Total

M Diamond = Memory Sub Total

You should also have:

M + = Memory Add

M - = Memory Subtract

Hope this helps.

Please remember to post a rating if I have helped you.

Have a good day.

Equals is used during a calculation of division, percentage, multiplication, etc. Use the total key or * key for a total of substraction or addition.
