Question about Texas Instruments TI-5630 Calculator

Open Question

TI-5630 won't total, or any other function button, + - x etc.

Only the numbers buttons seem to respond. Just gives me one continuous line of numbers, with no addition, subtraction, etc. of any other function.

SOURCE: Hello! My TI-84's multiplication, division,

Did it start doing it on its own? Or did this condition appear after you played some third-party game? If the last case is the correct one then the game may have reconfigured the keypad.

  1. Try to exit the game from inside the game.
  2. Remove the game from the Ram.
  3. Press [2nd][MEM][2: Mem Mgmt/Del][1:All]
  4. Use the down arrow to scroll along the list of objects in memory.
  5. Find the offending program.
  6. Use down arrow to point to the program and press [DEL].
If the program has an asterisk to the right of its name, it is archived. If you press DEL you will be asked if you want to delere it. Enter the number to the right of Yes and press [ENTER].
You may have to wait for the calculator to defragment the RAM.

What is factoring and give the examples


Quick-Start Guide When you enter an expression into the calculator, the calculator will simplify the expression by expanding multiplication and combining like terms. At this point the calculator will attempt to factor the expression by dividing a G C F, and identifying a difference between two squares, or factorable trinomials. Use the following rules to enter expressions into the calculator. Variables Any lowercase letter may be used as a variable. Exponents Exponents are supported on variables using the ^ (caret) symbol. For example, to express x 2, enter x ^ 2. Note: exponents must be positive integers, no negatives, decimals, or variables. Exponents may not currently be placed on numbers, brackets, or parentheses. Parentheses and Brackets Parentheses ( ) and brackets [ ] may be used to group terms as in a standard expression. Multiplication, Addition, and Subtraction For addition and subtraction, use the standard + and - symbols respectively. For multiplication, use the * symbol. A * symbol is optional when multiplying a number by a variable. For instance: 2 * x can also be entered as 2x. Similarly, 2 * ( x + 5 ) can also be entered as 2 ( x + 5 ) ; 2 x * ( 5 ) can be entered as 2 x ( 5 ). The * is also optional when multiplying parentheses, example: ( x + 1 ) ( x - 1 ). Order of Operations The calculator follows the standard order of operations taught by most algebra books - Parentheses, Exponents, Multiplication and Division, Addition and Subtraction. The only exception is that division is not currently supported; attempts to use the / symbol will result in an error. Division, Square Root, Radi cals, Fractions Division, square root, radi cals, and fractions are not supported at this time. A future release will add this functionality.

that's all I can say basically I learned it this way.

How do i use the x,t,e,n button


The function of that button depends on the current graph mode. It will give you the "n" only in the SEQ mode. Press MODE, cursor down to the "FUNC PAR POL SEQ" line, highlight "SEQ", press ENTER 2ND QUIT. Now pressing that button will give you the "n".

Graphing calculator argument error


The function you give as example in the additional information to your duplicate post is too simple to generate an Argument error. Maybe a syntax error but not an argument error.
Check what you enter on the line that defines the function. Do not confuse the minus sign - (for subtraction) and the change sign (negation sign) marked (-).
You can also reset your calculator by pressing the button on the back.

Answer always appearing


Minus and change-sign are two completely different things. Minus is used to subtract one number from another. When you press minus when the input line is empty, your telling the calculator to subtract. The only way it can subtract the number you're about to put in is to subtract it from something else, and that something else is the previous answer, hence the "Ans."

If you want to input a negative number, use the change-sign key. If you want to subtract one number from another number, use the minus key.

Try pressing the plus key when the input line is empty. You'll get Ans+ in this case as well, The same with multiply and divide, among others, and for the same reason.

E^ won't work


You are not using it correctly. To calculate the exponential of a number you use the key sequence [SHIFT][LN] to access the exponential function. Then type it the exponent (positive or negative) and close the parenthesis.
You do not use the power key (^)
The exponential function is not affected by the angle unit when you are using real values.

My son has a TI-84 Plus calculator and it is completely frozen. There is a message on the screen that reads " RAM cleared". Below that message it says "Press ALPHA F1-F4 to locate shortcut menus" but it...


The calculator OS has been upgraded to the version 2.53 MP.
For this version, whenever you remove batteries (or replace them) and turn calculator ON, you are reminded to Press [ALPHA][F1-F4] to locate Shortcuts Menu.
The calculator also asks the user to press either
[1:Do NOT show Again]
[2:Continue].

Here is what these cryptic messages mean.

Certain functions implemented on the new OS are available by pressing the [ALPHA] key followed by F1, F2, F3 or F4.
Since you may forget how to get to them, the calculator gently reminds you that there are other functions accessed only by pressing the [ALPHA] key.
It also gives you the option to flash the reminder every time the calculator memory is reset (CONTINUE) or NOT to SHOW the REMINDER again.

Usually after the RAM cleared message, press [2:Continue] or any other key but [1: ] to keep being reminded how to access the new functions.
Once a key is pressed the screen is cleared and you have the solid blinking cursor.

You must have used the TRANSFRM application before. It remains in memory and takes over the graphing function from the native OS. You must unload it from memory.

  1. Turn calculator ON
  2. Press the [APPS] button.
  3. Scroll Up (faster) or Scroll down till you see :Transfrm in the list of applications.
  4. Highlight that line and press ENTER.
  5. The new screen invites you to Uninstall or Continue
  6. Press the number key that corresponds to the Uninstall option (1:Uninstall)
  7. Return to your [Y=] editor screen to verify that the style lines have changed to the "normal" ones.

I have a Sharp EL531-WH, I am trying to use the 'data' button. I see it is shared with the 'M+' button with gray text above it, what button sequence do I need to push to use that button as the 'data'...


It is active only when the computational mode is set to Statistics (Standard Deviation). You press it after each data item. The M+ button allows you to add the content of the display to the independent memory (M). SHIFT M+ corresponds to M- and it subtracts from the independent memory the number that is in the display.

How do I add and subtract on this thing?


Hello,
I do know what calculator you have but on most calculators you have digit keys to key in numbers, operation keys (multiplication, division, addition, subtraction), function keys (log, exponential, %, square root, square or a power) and you have the = key to obtain the result of the calculation.

Press the [ON] button

To add 2 numbers, exemple 12 and 13
12 [+ key] 13 [= key]. Calculator displays 25, or 25.00 or 25.0000...

To subtract
13 [- key] 7 [=key] . Calculator displays 6 or 6.00, 6.0000....

To multiply
32 [x key] 5 [= key]. Calculator displays 160.

You may have memory keys, to store values. They may be labeled M to enter a number in memory, M+ to add a number to the one already in memory, M- to subtract from the number already in memory.

Hope it gets you started.
