You can store values in A, B,C, D, and M.
If you do not like the result recalled from a particular memory, Store the correct value in it. To clear the memories (default) store 0 in each of them.

Hope it helps.

How do I enter an unknown variable? Example 2(3x-4)

You have several variables but the only ones you have access to are the letters from A to F, the letters x and y, and the Memory M.
To store a value in variable x, enter the value, press [STO] followed by the key that has an x near it. To recall a value sotred in a letter variable press [RCL] followed by the appropriate key (the one that has a letter above it).
But you cannot do any algebra with this calculator, if that is what you are attempting to do. And please do read the manual that shipped with the calculator that is the best reference to the capabilities of the machine.

Hi & thanks. There is a small 'M' on the top center right of the 'number' screen. How do I get this to go away? Remove the battery? Thanks again & regards, -louis

This M does no harm. It merely reminds you that you stored something in memory. You can try pressing the AC (Clear All) button. Alternatively, store 0 in all the memories. If I am not mistaken you have 3 memories. Try
0 STO 1 to clear Memory 1
0 STO 2 to clear Memory 2
0 STO 3 to clear Memory 3.

TI-89 Titanium: I'm trying to enter a problem in which I can define two variables. For example, I would like "x-y|x=1,y=2" to give me an answer of -1, but that format doesn't work.

You can use the = sign if it is in a Function or, program as a loop. But, to define it you have to use the [STO-] key. Or store key. As in: [1 ] [STO-] [X ] [ENTER]
Next, [2] [STO-] [Y] [ENTER]

To clear Memory 1 (M1) store 0 in it
Para borrar la memoria M1, almacenar 0 en M1 (Google translate)

How do you enter your variable?

The memory locations A,B,C,D,X,Y and M are available to store values in them. M is the constant memory.
To type the name of, say, variable X, you press the ALPHA key then the the key next to which is the X in cyan/Green color. If I remember correctly it is the key marked with a parenthesis ).

However to store a value in a memory location or to recall a stored value you use the STO key to store and the RCL key to recall. To store or recall there is no need to press the ALPHA key.

After doing this division "7/4" I get the answer "1.75". I want to keep the whole number in one variable and the decimal part in another variable. What kind of program I could use to do that? Million of...

You may be able to find a program online that will automatically do what you want however if you don't have to do this too often you can just manually set "1" to a variable via the "STO-->" button (right above the "on" button-- select the value, pres sto-->, alpha and whatever variable you want) and set the ".75" to a variable.

Finding a program may be difficult for this type of program because you're trying to separate a whole number (essentially looking for a whole number and the remainder). You could always write a program for yourself but as I said before it might be a bit difficult.

Memory and memory recal

The STO> button just above the on/off button is your memory store initializer.
example: 2x + 53 STO> y
stores "2x + 53" in a variable named "y".
To recall, just hit y and enter. In fact, if you type an equation like 3y^2 - 4y it will insert the data in for every "y" and give you:
(2x + 53)(6x + 155) as an answer.
To clear the memory:
DelVar y or F6 (2nd+F1) and clear all w/ single character names.
To recall a prevous answer, 2nd+(-) or type ans(1) for the last answer. You can also type ans(2) for the 2nd to last answer & so on.
