SOURCE: Trying to find standard deviation on the calculator

I took statistics last semester and I don't really remember how, but after you enter your data, you press SHIFT, then STAT (on the 1 key), then I think it's under 5 (VAR), and maybe Xon-1? Eh, funny how long you remember this stuff for....

If you press the setup key then 1 under FSE it will say TAB (0-9)? enter the amount of decimal places you want and it will change that for you.

SOURCE: Combinations and Permutations

You can enter combinations and permutations.

If the order of the selection matters (ie. 1st, 2nd, and 3rd place out of 40 contestants) use permutation. Enter:

40{shift}{nPr}3 and then [=] for your answer set (=59280 possible ways).

IF order doesn not matter (ie. a team of 3 from 40 possible members) then it is a combination. Do the same as above, but substitute {nCr} for {nPr}. (= 9880 possible ways).

For your question: a three-digit set, selecting from 0-9. There is no specified order, it is a combination. The total n=10 (there are 10 digits in the range 0-9) and you are selecting 3.

so.... 10[nCr]3 with give the number of possible combinations.

The calculator was probably subjected to a hacking procedure. Buy another one.

Given the cost of the calculator, it probably will be much cheaper to just replace the calculator rather than paying for and installing a new screen.

MOD simply calculates the remainder that is left over after dividing by the MOD parameter.

For example, 10MOD7 = 3 since you can only divide 7 into 10 once, leaving a remainder of 3.

For larger numbers, eg 389487MOD31 you start by dividing 389487 by 31, which gives 12564.09677 (on the display), however you only want the fractional part so subtract 12564 to give 0.0967741935 . This includes the lower value digits that were previously hidden. Then multiply this result by 31 which gives 2.999999999 on the display. Since the result of a MOD calculation has to be a whole number, the answer needs to be rounded to 3. If the answer doesn't easily round to a whole number, it is likely that you have gone beyond the calculators working capacity.

An alternative method is to take the integer part of the first result (12564) and multiply it by 31 to get 389484, then subtract this from 389487, giving the answer of 3.

You've got the display set to fixed decimal notation. To change it, press SHIFT MODE 7 to switch to a scientific notation or SHIFT MODE 8 and then 1 or 2 to switch to one of the norm display modes.

norm1 switches to scientific notation if the magnitude of the number is less than 0.01 .

norm2 switches to scientific notation if the magnitude of the number is less than 0.000000001 .

norm1 switches to scientific notation if the magnitude of the number is less than 0.01 .

norm2 switches to scientific notation if the magnitude of the number is less than 0.000000001 .
