What is the difference between the "C" Button on a calculator, and the "CE" button?

.C=Clear\nCE=clear error\n All calculators have C button , some have both buttons. Usually CE clears the last input (in the window), but not the numbers stored in the memory, before the error occurred, that's why some calculators have also a CM=clear memory button and C button to clear all.

Standard computer keyboards have the @ above the 2 and the " above the '.\n\nThat's the way all keyboards are designed. I don't think there's a way to switch them around.\n\nI haven't seen the " above the 2 since the old mechanical typewriters.\n\nThis is the way it is now.  Every keyboard made is this way. I would really recommend getting used to it. It's not going to change.

Press a number x, the ^, and a number y.  For example:\n\nThe ^ key is next to TAN.

On a mac, it means your code is not gramticcally correct. On a PC I don't know but it's proably the same.

it really doesnt matter...\nyou could do a x b then the answer times c\nb x c and then the answer times a\nor c x a and then the answer times c\n\nif you have a calculator just enter it as a x b x c\n\nno matter how you multiply them you will get the same answer

the screen should say what button to press.  Common keys are Esc or Del or F1.  Failing that try checking the tech support page of your computer manufacturer.

In A1 type =20*2.3 \nin B1 type =40*3.6\nand in C1 type =A1+B1\n\nAlternatively, just type =(20*2.3)+(40*3.6) in C1\n\nDon't forget to format C1 for currency! Right click on that cell, select format, then the number tab, select currency the pound symbol and 2 decimal places

0.7 * 10^2 or 0.7 E+2 in some calculators,\n\nmeans that you must take your decimal (0.7 in this case) and shift the point a number of times as the exponent says (in this case 2) to the right if it is positive (like in this case) and to the left if it's negative.\n\nIn this case you must move the point two steps right: \nfrom 0.7 to 7.0 (first step) and then to 70. (final answer)\n\nAnother couple of exemples:\n\n.35 E-6 (or 0.35 * 10^-6)\nyou must move the point six steps left:\n0.00000035\n\n0.445 E+10 (or 0.445 * 10^10) \nyou must move the point 10 steps right:\n4450000000.

Depends on the model...\n\nOn the Texas Instruments (TI) models, you would use the GCD function.\n\nGCD is found under MATH → NUM, arrow down to gcd( \nFrom the home screen, choose gcd(  followed by two numbers separated by a comma.\n \nNOTE:  gcd( accepts non-negative integers only and works with only two entries at a time.  If you need to figure the GCF or more than two numbers, do them a pair at a time.

Well, they both take a lot of time! And, I must see the algorithm of (....;)! When both take a lot of time, We should check the one which takes the less time! If both takes the same time, we should choose the one which takes less space (Memory space I mean) But generally, Prefer the 2nd one! I think we should try to use a general code or function in the second choice! If there isn't a general rule, then, I prefer using the 1st one, cause it takes less memory and the lines of codes will be less I suppose...

Consider holding down the Alt key whilst typing 253 on the numeric keypad - it would make this easier to read:\n4r²-25s²/2r²+3rs-20s\nor should it be:\n4r²-25s²/(2r²)+3rs-20s\nor:\n4r²-25s²\n--------\n2r²+3rs-20s

The standard calculator uses the ^ button.          The ^ means: to the power of. So, to write 5 to the power of 4, you type 5^4.  Hope this helps.

I'm not really sure I understand your question correctly, but computers work using only two digits, 0 and 1 (sometimes referred to as 'off' and 'on', like a light bulb).  As a result of that, pretty much everything that happens inside a computer is based on 2 (= even) numbers.

minus should be negative and iy doesnt say if it is C or F

Underscore is this character _  You can find it near the backspace button. It's the button with two lines on it. If you press it while holding shift  you get the underscore _
