Combinations Of Numbers To Equal One Total

Forum Register
Search Excel Forum Posts, Tutorials, Macros, Tips, and More

Hello gurus!

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!!

HELP!!

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,
Jenny

Hello everyone, I am new to this forum and have been using excel for about 3 years. I have learned alot but still can not figure out how to make numbers add up in one box like a running total. Meaning, If I have a list and in the list is one cell for each item say like cell a1 is for a can of coke and cell a2 is for a car tire and so on,and i want to keep a running total by adding a number to cell a1 or a2 like say "3 i.e. 3 tires or cans of coke" and later that day i come back and need to add 2 more ......so i want to be able to just click on the cell a1 or a2 and enter the number 2 and the cell would add the number in it to the number im adding to it to show a result of 5 tires or whatever. I am sorry If i am not asking the question in an understandable manor but its the best way I can think to ask it.lol anyways, any help would be appreciated, Thanks in advance.

First time in this forum. Hi all. I have a challenging question, is there a way either by VBA or manually (preferably both, if possible) to actually unite the X amount of numbers that are in a cell given the contents is alphanumeric? I'll give you the following examples to see if you can understand what I' referring to?

DATA output should be
asd67,h876 --------> 67876
2,3,ujdj5&34 -------> 23534
909k86m34 --------> 9098634

Hope this makes sense?


Hi there, I have a string of numbers and I would like to add zeros to the end of it.

For example my numbers are formatted like this: 1234 and I would like to add zeros to the end so it looks like this: 123400 (no decimal).

I would do it manually but I have a column of over 2000 different numbers.

Thanks for your help, you guys are great!

Hello,

I'm a bit of a newbie with Excel, but...

I have several cells with data that contain both letters and numbers (4H, 8V, 4FH, etc.) What I want to do is remove only the text characters from these cells, and add the remaining number values together among a series of cells with this data type.

If your answer involves using a macro or VB, please provide a link on how to use the formula. I've never used a macro or VB.

Thanks.


Hi folks,

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


Hello All, I have a column where cells need to be 50 characters long, it contains addresses, however, since all the addresses do not meat the criteria, I need to add (blank spaces) to reach the 50 characters, any idea on how to approach this?

Example

Fire Street #50 this cell contains 17 characters therefore I need to add the rest by adding blank spaces to reach 50 characters, otherwise the system I am exporting the data will not understand this cell


Is it possible to have numbers added to the same cell and have excel continue
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?



I know this question has been asked a bajillion times, so I apologize for the redundancy.

I am working with an Excel spreadsheet and saving it as a .csv file in order to upload to an application that parses out the .csv data as transactions. The system requires .csv files, so this is how I need to save my doc (with this extension). I have been successful at preventing Excel from coverting that long number into scientific format. I have saved as a TXT file, pasted the longer number and it displays correctly. That is all good. But I have to save as a .csv. So if I do that, close the Excel window, and then open again (as the .csv file), the numbers are back to being displayed in scientific format. I have tried creating an Excel doc from scratch and entering text in Text format, to see if this created a cleaner file. But again, the second I save as .csv, close the window and then open that file up again, that dang scientific format is back.

Does anyone have any idea of how to work around this? Once I have successfully gotten the numbers to display as the long-chain number, how can I get them to "stick" so that they don't revert back to scientific format when I reopen the file?

Thanks so much for your help!


Ok, I'm going to try and explain this. I am going to have 5 data points in cells such as A2:A6

All I need is to know if there is an upward trend or downward trend of the numbers.... I can't have something that simply takes the first and last number and checks if it's higher or lower. I need to actually see if they are trending upwards. Also how would i go about making it so that if they are trending upwards it shows an up arrow, and down arrow for downwards...

And finally, if the trend continues at the same rate, how long it will take the number to reach a goal. Each data point will be 1 week apart, with an ultimate goal needed to be achieved at the end.
This will be a completely separate formula on the sheet....

Any help?

Is it possible to assign values to names in a list, so that when you validate
it as a drop-down list, you can select a name from the drop-down and it's
corresponding value will be added to separate cell? Basically, I have survey
questions which have five possible responses: Excellent - Very Good - Good -
Fair - Poor. We want to assign a value to each, 5 for Excellent, 4 for Very
Good and so on, so that when a response is selected from a drop-down, it's
value appears in a separate cell (so that we can calculate a total and
average score from the selections).

Thanks

i've been trying to figure this out on my own but seem to be hitting road blocks.

i have a column of numbers that we extracted from a database as whole numbers. for instance, 30 should be .30 and 100 should be 1.00. when i try to increase or decrease the decimal point it doesn't allow me to convert it to those positions.

would any one have a tip of how i can easily convert this? there are over 2000 entries in my excel spreadsheet so to do it manually would take a lot of time/effort.

thank you!


In excel, I tried to convert numbers to number format, using
format/cells/number from the category list. But it won't take, and stays
text-like. Any ideas?



Thought I'd append my experience of the above problem - you can find all sorts of references to it everywhere.

My problem was that a userform defined with Excel at work (containing DT pickers) gave the message in the title when opening it at home. I had a light-bulb moment and wondered whether there was a difference in the version numbers for MSCOMCT2.OCX at work and at home. Turned out the work version was newer. I then copied the MSCOMCT2.* files from work, made a backup of them at home and copied those from work to my C-drive (Windows XP - c:\windows\system32\ ).

No luck. I then rebooted the machine - still no luck.
Then, finally I unregistered the old DLL via
Code:

regsvr32 /u c:\windows\system32\MSCOMCT2.OCX


(not sure if this was necessary, but I didn't think it could hurt). Reregistered the DLL via
Code:

regsvr32 c:\windows\system32\MSCOMCT2.OCX


and what do you know - it worked.

Summa summarum - it could be an idea to check whether the two machines have different version numbers for the MSCOMCT2.OCX files.


Right now I have a sports league with 8 teams, I'd like to create a random 7-game schedule where each team plays the other team only once. Essentially this will be a 7-game round robin. However, I'd like to be able to use this for any number of teams and games.

I'd like to do this in Excel, but I can't figure out how to have a randomly generating non-repeating macro with text values in cells.

So right now I have a column of 8 values and need matrix of 7 columns by 8 rows next to it.

I've found this thread that has one for numbers, but I can't figure out how to do it for text values...

I'm trying to write a formula that will automatically take a group of football (soccer) scores, compare them with a set of predictions, and then allocate points according to how close the predictions are to the actual scores.

E.g.
Manchester United 3 - 0 Arsenal
Prediction: 4 - 1
Points: 1

I've found a formula online that works for most scores; the correct score (e.g. 3 - 0), a correct win (e.g. 4 - 1), and in the case of a draw (e.g Man Utd 1 - 1 Arsenal, and the prediction 2 -2), correct draw (but not the correct score). The points are as follows: Correct draw (Prediction = result): 4 Correct win (Prediction = result): 3 Correct win, incorrect score (Winner correct, score not): 1 Correct draw, incorrect sco 1

The formula I found online for all but the correct draw is: =IF(A3&B3=C3&D3),3,IF(AND(A3=B3,C3=D3),1,IF(AND(A3>B3,C3>D3),1,IF(AND(A3<B3,C3<D3),1,0)))))

Could someone help me work out how I can write a formula to add before the above that will check the contents of four cells (the home score, away score, home prediction, away prediction), and if the number in all 4 cells are the same, allocate 4 points? I've tried using averages, but some combinations would void this. I've also used the SUM function, but the same happens, as with MULTIPLYING.

Something like =IF(A3:D3) are equal, 4,0

Below are a few examples of what I mean:
(Result) (Prediction) (Points)
A B C D E
3 - 3 3 - 3 4
2 - 1 3 - 1 1
1 - 0 1 - 0 3
3 - 3 2 - 2 1

Apologies in advance if I haven't explained this clearly enough.

Thanks

Hi,

I have a long list of data validation. I was wondering if there is a way when I clik on the drop down menu and type the first letter, automatically Excel shows all list with that letter.

Right now, I have to click on the drop down menu and scroll manually until I reach that desired list.

Thanks.


Hello ,

Here is my issue:

I have a list of SKUs in Excel and I need to add one same word to 500 cells that have pre-existing text in the cells. See example below:

1) List of SKU's in cells:

34
35
39
55


2) text that needs to be added IN FRONT of every number:

DF

So the result would be:

DF34
DF35
DF39
etc.

How do I do that in a formula and not manually? I found another similar thread and I understand how to do it from the instructions there but the same text goes on the back and the result is: 34DF but I need it to be like: DF34.

I am using Office 2007 for mac.

Thank you for the help,
Chris
