Random Number Generation Without Repetition?

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.

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!

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

I am trying to figure out how to write a formula to figure out production cycle time.
We will be building 8 "widgets" a day.
We will work 10 hours a day.
There is a 20 minute break at 9:20 am.
Production shuts down for lunch 30 minutes for lunch at 12:30.
Production starts at 6:00 am.
Here is what I can do.
Production cycle time = (10*60)-30/8 or 71.25 minutes
If we start at 6:00 am, the first scheduled cycle completion time = TIME(6,0,0+71.25/1440)

My problem is when I am trying to use a logical "IF' statement to account for the 20 minute break or lunch and still calculate the end of each cycle time through the day I receive a number of error messages.
This is the formula I am trying to make work. I have the cell the formula is in, formatted with a "mm,ss" format.
=(IF(D4+G1/1440>9:20,(D4+G1)/24,(D4+G1+15)/1440))
I have included an attachment to help (a picture is worth a thousand words).

Any help will be greatly appreciated.
I have bought a number of books in an attempt to figure this out, and I am still stumped

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!

I have an extensive spreadsheet with several columns and all showing borders
where each cell/column begins and ends. However there are a few cells where
the break with the next cell does not show the line.

I have highlighed the cell in question, gone to format/cell/borders and
everything looks fine. Black color + format border shows square with all
sides of square showing.

Any thoughts on how to fix these few random cells.

Thanks

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 need help writing a formula to add a column of numbers until a value is reached, then start over adding numbers starting at the next cell after the value is reached.

Thanks for any help.

Hi All,

I am trying to make excel automatically add a leading zero to values which are 5 digits long;

i.e. number input is 15185, then excel automatically changes it to 015185.

If I put a Customer Number Format of 0##### it works, however, a user could put any length of number into these cells, and if the number is less than 5 digits I don't want a leading zero.

Is there any way of writing a small macro to sort this out.

The numbers would be input into range B16:223.

Many thanks,


Andy

Is there a worksheet function that will generate all possible combinations of
a set of given numjbers. For example, 1, 3 and 8 would generate 138, 183,
318, 381, 813, 831 and so on...

dear supervirsor
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
changed it still in english

A previous poster explained what I also need; there were no responses,
so I thought I would try again.

Does anyone know of an Excel template--or a small stand-alone
program--that will calculate the interest/principal breakdown when
payments are varied in amount and frequency? Free or low-cost, please.
I need one that will work on my Mac/Office 2004. I will need to print
out periodic reports.

Here is the way the previous poster described it:
"Excel template: Loan Amortization for random/irregular payments,
figures days
between payment dates.
I have a loan with a variable beginning balance and irregular payments
with
annual large payment. (based on collections)
Would like to enter payment and date.
then Excel would figure days since last payment, interest amount,
principal
amount, Ending Principal balance.
And total interest paid, total pricipal paid
If I change the starting principal, excel would recalculate all
entries."

Thanks very much.

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!!

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!

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.
