Question about Microsoft Comfort Curve 2000 Keyboard

Did you check the numlock key? If numlock is off, then the number pad becomes extra arrow keys, which may well adjust your volume, or do other strange things

The CPT button is used on the TI calculators to tell the calculator to compute the value instead of storing one. The HP calculator knows whether you just typed in a number or not, and so it can distinguish without the need for such a key. Thus to calculate a particular value after entering the others, you can simply press the key for that value without bothering with any CPT key.

As for the maturity yield, without knowing exactly which value you want, I'm afraid I can't tell you which key to press. Could you reply to this post and specify that? What key do "they" use on what calculator?

To enter an exponent of ten (EE), use the x^10^x key on the bottom row of the keyboard, between the decimal point and Ans keys. To raise a value to another value, use the x^ key to the right and below the circular cursor pad, between the x^2 and log keys. To raise e to a power, use e^x, the shifted function of the ln key on the rightmost column of the keyboard, between the logab and tan keys. To change sign (+/-), use the (-) key on the leftmost column of the keyboard, above the RCL key.

To enter a power of ten, use EE, which is the 2nd function of the , key just above the 7 key. To raise a value to another value, use the ^ key just above the divide key.

Press the square-root key, type in the value whose square root you want, then press ENTER.

If it's part of an expression, instead of the ENTER press ) to balance the opening parenthesis the calculator automatically puts in and continue typing in the remainder of the expression.

Make sure, when you entr a formula that you hit the ENTER key instead of just moving to tyour next cell. To have all numbers added or moved, use the"Special" application, or change the value. Such as -if you are working in text mode and you enter numbers, they are only numbers in text mode. They don't have a value. Correct the cells to reflect numbers. Right click, format cell - select what you want.

Hello,

I dont think you got a lemon.

You acn always enter the powers of 10 as 10, [y^x], but is is less efficient than the EE key

This EE representation is a shortcut.

If you want 10 to the 5th power you just enter [2nd] [EE] 5 and the calculator displays 100000. Of course if you need any other number multiplying the power of ten you enter the following e.g. 2.677[x][2nd][EE]5.

You will not get any error with a positive exponent. But if your exponent is negative you should use the change signe key to the left of ENTER and symbolized by (-)

To avoid all errors I would use parentheses to enclose my exponent.

Here is how to explain the seemingly erroneous result

10 [EE] 5 ) (-) is interpreted by your calculator as 10x(10^(-5)) which evaluates correctly to 0.0001 because [EE] by itself stands for 10^ .

Hope it clarifies this point for you.

By the way some new calculators (Casio) don't have this EE key. Instead you find a key labeled x10^X .

Hope it helps

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.

The LOG and LN keys do what you have done.

To get 9 to the 16th power, enter 9, "y to the power x" (under the OFF key) then 16, then =

3 to the 12th power is the same, enter 3, y to the power x, 12, =, result 531,441

The inverse key sequence: value 1, 2nd, y to the power x, value 2, returns the xth root of y, e.g. 531,441, 2nd, y to the power x, 12, =, gives you 3 back

Probably a value stored in the "x" variable (guessing x=1)

try the following, type or look for the "Define" function: Define X=X and see what happens, also try Cleaning the variables "F6>cleanup, etc" as a last resource do factory reset, but first archive your important files (not very recomended as some of them may contain the variable's value and just not solve this)
