How can I repeat the same divisor without having to key in the number every time

Hi Steven:
You should be able to key in the number, then press (memory plus).
After that, press (clear) once. That should leave the number in memory but leave the display at zeroes.
- 1) Then you would enter your number, Press (divide) symbol, then press (memory recall), then press (equals).
The answer should display. Press (clear) once. resets to zero
- Repeat (1) as above for next numbers.
Hope this helps.

Somehow I have pushed a button I wasn't supposed to. When I turn the calculator on there is an 'M' on the screen. I cannot remove it. This makes my totals show up with out the cents column.

There is a couple things we can try, press the clear button on the calculator, failing that! remove the batteries for at least 60 seconds to see if it will clear "M stands for memory" the only other thing you can do is locate the M key, press once engages the memory, press again turns it off on some models.

TI-83 Plus ram cleared message when turned on

It calculator tells you Ram Cleared each time you turn it on, the most likely reason is that the backup battery is depleted. Its role is to keep the memory modules electrically refreshed when calculator is turned off. If the backup battery is dead, the memory is erased when you turn calculator OFF. Main batteries no longer supply power and the contents of the memory are cleared.
  1. Check that main batteries are good and inserted in calculator.
  2. Turn calculator OFF.
  3. Replace the backup battery.
  4. Turn calculator ON.
  5. Press the [CLEAR] key to erase the "Ram Cleared" message.

When I go to clear the memory and hit 2nd Mem.. I get nothing. The calculator seems to be locked so i cannot clear the memory

As the first step to you diagnosis remove the Main batteries out of the calculator and leave them out for a while. The memory should be cleared.
If that does not restore your calculator you may have to use the procedures suggested by TI for calculators that do not turn on.

Hope it helps.
Thanks for using FixYa.

What does MC,MR,M-,M+ on the calculator mean and do?


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!!

Lost manual

First clear all w/ ON/AC.
Enter the tax rate desired eg. 7 for 7% (can you tell I'm in PA)
Press RATE then TAX+
Press C/CE.
The next time you use TAX+ it will calculate and add the value that you set.
Do the same for TAX-, you can use a different value for each as they are separate memories.

I have a Canon F-502 calculator, without guide, and I can't seem to figure out how to clear the memory. Should be simple but !!!!!

To clear the memory on a Canon F-502, press the X->M button next to the MR button. You will see the "M" letter disappear in the screen and your memory is now clear. Hope this helps!
