I think excel will give me the montly covar and var and I need to annualize these numbers. Is there a way to do this in excel?

Hoping someone can help me quickly as I'm pulling my hair out and have a deadline getting too close.
Been trailing the net and this board but can't work out how to do a simple variance.
How do I work out the difference between two numbers - including negatives.
If the numbers are all positive, it's fine as it's simply a case of A - B = C which is your difference. However, that doesn't work if B is negative.
I need a formula that would give the following:
First Number / Second Number / Difference
1 / 5 / 4
1 / -5 / -6
-1 / 5 / 6
-1 / -5 / -4
-5 / -1 / 4
Hopefully there's a simple function I've been missing.
Thanks in advance, R
It looks like this:
=(E3/((A3+D3)/2))*12/months
So if I substitute with some actual data:
=(6/((22+33)/2))*12/months the answer becomes 21.8% (as the annualized voluntary turnover rate).
What does the *12/months actually do mathematically? I cannot find it in the excel help files and have not been able to figure this out using math (on the calculator).
I need to know the formula (if there is one) for Excel to figure all the possible combinations of a given set of numbers that will add up to a specified sum.
In other words, if I give the following numbers 1, 2, 2, 3, 3, 4, 5, 5, 6, 7, 7 - I want Excel to figure all the possible combinations that will add up to 23, and also SHOW ME those combinations, and not just HOW MANY combinations there are.
i.e. one possible combination is 2, 2, 3, 4, 5, 7
Can this be done? What is the formula? I'm having a hard time figuring it out!!
Desperately,

The Geomean function doesn't work because it only uses positive numbers.
Any help would be greatly appreciated.
Cells accept hours over 23,
Adding cells in column returns correct total time.
Have not found a way to multiply these cells by a $ hourly rate.
So use HOUR(cell ref) and MINUTE(cell ref) to capture values in referenced
cell - then use these values to calculate total payment for $rate per hour.
However, the HOUR(cell ref) formula returns the hours in excess of 24 when
the cell contains an hour value in excess of 23 (ie 27 hours returns 3).
can calculate overtime hours. In california over 8 hrs in one day is
overtime. The 8 would be considered regular hours and anything over is OT.

lets suppose my numbers a 1,2,3,4,5,6,7,8,9,10,11
I want to generate all possibilities of the 6 numbers. But i dont want duplicate series.. I mean 1,2,3,4,5,6 and 6,5,4,3,2,1 are duplicates.
ANY HELPS ARE GREATLY APPRECIATED
to calculate the addition for me in that same cell......ex: I have the number
8 in cell d2 and I want to add the number 8 to that cell and have excel add
the 8 to the previous 8 for a total of 16 in the same cell.....the next time
I would add 5, and the total would be 21? Can this be done in a single cell?
date range that was provided, and to return Early, Late or Ok accordingly.
DATA output should be
asd67,h876 --------> 67876
2,3,ujdj5&34 -------> 23534
909k86m34 --------> 9098634
Hope this makes sense?
On excel, if I divide 462,534.05 by 335 I get 1,380.70. Then if I times 1,380.70 by 335 I get the SAME result of 462,534.05.
I have to account for the difference of not dividing equally so there is some format or accounting function that's preset that I don't want but I have no idea how to fix it or format my excel sheet to calculate as my calculator would.
Please can someone help? Thanks!
Thanks!
Here's my question...I have a list of numbers and I want to know how many combinations (and what they are) of adding the numbers will equal an amount.
e.g.
List of Numbers
1
2
3
4
5
6
7
8
9
10
Amount to be reached = 12
These are some of the possible combinations to reach 12 :
2+10
3+9
4+8
5+7
3+4+5
6+3+2+1
Is there a function in Excel that will do this for me? I want to know which numbers (i.e. cells) can be added to reach 12. AND, if possible, colorcode the cells added for each combination.
Good luck and thanks!!
I'm really hoping someone can help me with this...
I need to plot percentages over time in a line graph in excel. I don't want to have to do a percentage equation in the spreadsheet, I just want excel to take two sets of values and display the percentage in the chart. For example, I need B1 as a percentage of B2 for week 1, C1 as a percentage of C2 for week 2, etc....
Can someone please offer a suggestion for how to do this? I would really appreciate it.
Also, would it be possible to link data from other sheets in the workbook into one single chart?
i would like to know how to change english numbers to arabic number on excel
, where when i change the language from english to arabic the numbers didnt

difference where the times cross midnight. Example:
Start time: 23:50:00
End time: 00:15:00
How would you formulate an equation to determine the duration of time or
differnce between the start and end time?
Received Date & Time: 10/29/2010 3:27:00 PM
Completed Date & Time: 11/1/2010 3:57:32 AM
Business Hours: 08:00 AM to 05:00 PM
Non Business hours: 05:00 PM to 08:00 AM
Weekdays : Monday to Friday
Weekends: Saturday & Sunday
If I calculate TAT for this time period it should show me 1 hour 33 minutes, why because business hours are closing by 5:00 PM on 10/29 so it should not calculate duration after 5:00 PM to until 08:00 AM on next day, however 10/29 is Friday so formula should calculate the duration from 10/29 Friday 3:37 PM to 10/29 5:00 PM and again it should calculate from 8:00 AM on 11/01 Monday and formula should skip Saturday & Sunday.
In this scenario I have completed the task before 8:00 AM on 11/01 so it should show duration of 1hour 33 minutes.
Please let me know if you need any more details
triangle. I copied it to create a new data set and used find &
replace to change the worksheet references to the new ones.
The cells still contain the result of the old formula referring to the
previous worksheets. The only way I can get the formula to return the
correct result is to edit (F2) each cell and press enter. Calc now
(F9) does nothing.
I've seen this before, but this time, I need to calculate many
thousands of cells and don't have time for this workaround.
Any ideas?
Thanks.

I have two columns of data: column A contains the date and time in the form dd/mm/yyyy. Column B contains a number value. All the times are in order, so column A looks like:
01/01/2007
02/01/2007
03/01/2007
I have data from 2007 to 2010. I need to calculate an average daily value (in column B) for each month, and display it in column C. So, for January, I need to calculate the average of 31 days, February, 28 days, etc.
Is there a function I can use to do this? I've been trying the AVERAGEIF formula but can't get it to work. Any ideas would be much appreciated!
Many thanks,
Caitlin
