Find All Number Combinations In Dataset That Add Up To Specific Number?
Jun 3, 2014
I have attached an example. If I have a set of numbers such as the one attached, is it possible to create a formula that will show me all the combinations of numbers that add up to 55.52? In the attached I have highlighted in different colours all the number combinations that add up to 55.52. The numbers highlighted in blue appear within more then one combination. Is there a formula that can do this for me, instead of randomly adding numbers hoping they add up to 55.52.

I have a code that generate some combinations for a specific sum from a given data set. This code has two errors.
1. code does not look into data. it generates
2. Code generate those combinations for which sum is greater than target value.
E.g. first combination code generates is 3+7+10+12+12
This wrong by two means sum is
1) 44 while we need 40
2) 12 is not in data.

What I am looking for is to select between 7 and 15 numbers in total, I want all the possible 6 digit combinations for this.
EG: if I choose 2,9,11,13,15,17&26, it would look something like this
2,9,11,13,15,17
2,9,11,13,15,26
9,11,13,15,17,26
And so on.
If I chose more numbers (10) 1,2,3,4,3,6,7,8,9,10 it would start something like this
1,2,3,4,5,6
1,2,3,4,5,7
1,2,3,4,5,8
1,2,3,4,5,9
1,2,3,4,5,10
And so on.
Please remenber I would like to be able to secelt between 7 and 15 number and be given all the possible combinations.
I would like it to be in one sheet but if that can not be done on as many as it takes.
It would be good if I could just type the required number into A1,B1,C1 and so on and they just gave the combinations required.

I have a spreadsheet that contains dates in format mm/dd/yyyy. Lets call this Column C(Paydate). In Column A I have a date that needs to be a 2 business days before the paydate. If this date in column A winds up being a Saturday or Sunday, the function needs to return the previous Friday. If the date is any weekday then it should return that weekday
For example:
C1 = 10/18/2013(a Friday) then A1=10/16/2013
C2 = 10/14/2013(a Monday) then A2= 10/11/2013(the previous Friday since 2 days before 10/14/2013 is a Saturday)
C3 = 10/15/2013(a Tuesday) then A3= 10/11/2013(the previous Friday since 2 days before 10/15/2013 is a Sunday)

I have a column of references I wish to standardize. Contained within a general text description there is also an order-specific reference number, which is not relevant for my purposes. I wish to find all of these numbers and replace them with nothing (i.e. retain the rest of the description).
The reference numbers are always in the format "P#####/##". Unfortunately these references are in the middle of the text field, not at the start or end, so I can't use a LEFT or RIGHT formula to delete them.
Once these reference numbers have been deleted I will then be able to filter for unique records only. When I do this at the moment the filtering has no effect due to these specific reference numbers.

I'm trying to count the number of rows in a dataset where column A is something, B is something, C is something, D is not something, D is not something else, and column E > 0 OR F is something but I just can't get the result I want.
My actual dataset is a staggering 294,000 rows and 46 columns so here's a simplified version:

I am trying to find a way of counting the total number of days medical devices were in-situ for a fairly large dataset.
The worksheet has a few thousand rows. Column A - unique identifier for patient; column B - date inserted (Aug 02 - Aug 13); column C - date removed or audit date. There is no missing data, all rows have both dates. Some devices in for few days or weeks, some for up to 7 years.
I want to count each 12 month period (starting 1 Aug 02) the total "device days" for that year. (e.g. if device inserted 1 Feb 03 and removed 1 Apr 03, in year period starting 1 Aug 02 would have been in for 59 days. Another device inserted on same day and not removed until 9 Sept 05, would for first period (01/08/02- 31/07/03) 181 days, second period 366 days, third 365 days and fourth (01/08/05-31/07/06) 39 days). Therefore for the two rows, the first period total would be 240 days (59+181).

I want to have a sheet with all the previous drawings for the florida lottery.
Then I want excel to ask me how many numbers do I wish to play.
Then when I say 12 (for example) it would pick 12 numbers from 1 to 53 and match all possible comibinations of thoses numbers to the the previous drawings and tell me wich 12 number combination would have won more times then others. So it would need to compare each possible 12 nmber combination to each other and see wich one won more 6outof6, 5outof5, 4outof4, and 3outof3. Then give me the one with the highest winings

Here is what my table kind of looks like
A B
4 0.25
7 0.3
2 0.1
3 0.15
4 0.30
1 0.4
8 0.05
2 0.1
Now there is the number and the number(A) that it value it represents (B). This is what I want. I want to see all possible number combinations between the upper and lower A columns listed veritcally under the whole set, with out duplicating any numbers and with the upper numbers only being in the 1st position and the lower numbers being in the second position Ex( 4-1, 4-8, 4-2, 7-4, 7-1, ect, ect (listed vertically). Now in column B under, right beside each possible combination I want to see the result of the two values multiplied (ex. beside 4-1 I would like to see 0.1)
So below that mess listed above I want to see something like this
A B
4-1 0.1
4-8 0.0125
ect
ect
ect
I want to be able to swith the values around and have it automatically make the correction.

I wish to calculate the total number of combinations using the number of entries in 6 fields regardless of what the actual entries are. In other words only the number of entries are relevant. They look as follows for example:
Field A1=4; Field B1=3,5,12; Field C1=9,2,11; Field D1=14,1,5; Field E1=18,2; Field F1=3,7
Calculating it using a calculator is too tedious since I have several rows of data with similar entries. I just need to know what the total number of combinations are eg in the above example 1X3x3X3X2X2=108 using some excel formula.

Any method to determine the number of instances a value ("4" for example) appears next to a specific value ("x" for example). I don't have a workbook; I'm just looking for any formula that can search for specific values and find the total number of instances that an adjoining cell contains data.

I am working on a concrete pour summary, I would like to have the specific codes on each tab be affected from one summary page. So when I enter a certain number on sheet 1 , it will affect that same number section that is on a different sheet. It will be adding a certain amount to that code section every time its entered. What functions need to be used to make this work..?

I wrote an excel program in Excel'03 for a dental office to manage state assistance patients and one of the table columns is the state assistance number. The problem is that the program defaults to a number format when it is entered instead of a text format, which is what I want. The issue is that state assistance numbers are always 8 digits and when it defaults to a number field the program drops the required preceeding zeros.
For example the number 00123456 will sometimes show up as 123456, which is wrong. It's like sometimes it will show up right and other times it gets a butterfly in its brain and deletes those zeros irritating the receptionist here. So, how do I get the table to either stay in text format or set up a number format that keeps the preceeding zeros?

im looking to piece together all possible part number combinations with a one condition:
The values in Column A must come before the values in Column B. The values in Column B must come before the values in Column C. And So forth...
Example: If Column A had the values of A, B, C; Column B had the values of -1, -2, -3; and Column C had the values of -01, -02, -03
The outcome(s) would be: A-1-01, A-1-02, A-1-03 and so forth...
How can I get it to do that? But I need the flexibility of adding on more "options" should the part number be bigger (for future part number combinations).

After looking at other similar post titles I could not find a formula to work exactly proper.
I have attatched a sample of my problem. What I need is for cells E4:J4 to look for a match in cells B4:B16 and give a value of " Yes or No " in cell K4 if a match is found. Then copy down formula through E5:J5 to B4:B16 - E9:J9 to B4:B16. As my examples indicate Cells K4 would = yes, K5 = yes, K6 = yes, K7 = no, K8 = no, K9 = yes. Column D is the results, Columns E-J represents all combinations of column D.
I have tried the following formulas but they did not work entirely correct.
= NOT( ISNA( MATCH($b$4:$b$16, e5:j9, 0 ) ) )
= COUNTIF(e9:j9,"="&b4:b16)>0

I am looking to do the following:
Say I enter the following values into a spreadsheet:
5
7
4
24
32
Is there a way to enter the value "36" and have Excel find the two values of 32 and 4 which add up to 36 for me? I will obviously be dealing with much larger spreadsheets and would like to somehow save time by not having to hunt down possible combinations of the total value I'm searching for.

How to translate a specific number into a specific letter related to the number itself.
I have lots of different numbers for example all going down a specific cell (These numbers I want to separate into 3 different catagories. The positive numbers I want to be calculated as the same Letter that is next to that row directly over to the left of that cell.
So if the letter
B / cell / cell / +9 / Then I want if its a positive number like +9 to answer in the formula with the same letter (B) listed to the right in the same row in a different cell of course
B / cell / cell / -6 / Then I want if its any negative number like -6 to answer in the formula as the opposite Letter of (P) listed to the right in the same row in a different cell of course
P / cell / cell / +17 / Then I want if its a positive number like +17 to answer in the formula as the same letter (P) listed to the right in the same row in a different cell of course
P / cell / cell / -3 / Then I want if its a negative number like -3 to answer in the formula as the opposite Letter of (B) listed to the right in the same row in a different cell of course
and thirdly if its a (0) zero and only (zero's) Then I want the answer to stay (0) zero.
The number can be any numbers it doesn't matter. Only distinction is that positive number of +1 and up repeat and stay the same letter that the cell on the far left is already stated.
and all the negative number of -1 amd below all reverse the letter to the opposite letter of (B to a P) or (P to a B) listed to the right in the same row in a different cell of course
and of course (0) zero would be listed as a positive number and only return a (0) zero as the result of the formula.

I would like to create a vba script when ran an input.box comes up and asks you to "enter number you want to start numbering from" and when the number is entered in the input box. e.g "7654", excel starts numbering each cell in column A from 7654 until there is an empty cell in column B.

How can I generate all the combinations a 3 digit number produces? Example 123 can be written as the following:
123
321
213
312
132
231
I THINK this is all the combinations it will produce.

I am trying to find a way to calculate the number of hours between date/times found in separate rows. The attached data set will help to envision what I am talking about.
For each couple of rows, I need to find a way to calculate the number of hours elapsed from row 1 to row 2. In the first example, to calculate the number of hours between 12/2/2009 8:56:51 and 12/4/2009 6:35:27.

A1:A10 contains text (say colors) and B1:B10 also text (say vegetables). I need a formula to count the number of times a certain combination of numbers and vegetables appear in the same column, so if "red" and "carrot" appeared in A4 and B4 and also in A6 and B6, the result would be 2.

I have 7 columns x 3 rows with unique numbers. I wish to determine every combination of the above numbers without repeats.
5
11
17
24
29
35
40
[Code] ........
Column 1 would only use column 1 numbers.
Column 2 would only use column 2 numbers...etc.
Also have the same for 5 rows of unique numbers.
I've been working on this for 10 years and this is the last step to finalizing the WINNING numbers.
Back checking using the 5 row technique I would have spent 10,000,000.00 playing over 8 years with a winners purse of 33,000,000.00
With the 3 row I would have spent close to 200k and won 2.5 mil.
Only problem is that I don't have the 10 to start with, the 200k is a maybe .
I need to be able to generate the combinations to play the numbers.

I have a large amount of data and I'm trying to count how many unique values I have in one column. I also want to know how many times each duplicate appears. I tried using a pivot table but it's not working for me.
I also tried the following formula: =SUM(IF(FREQUENCY(H:H,H:H)>0,1)) but it's not quite working.
