Write down the number in cells for Example:

A1 (59) Without Brackets

A2 (50)

A3 (80)

A5 ? ANY Number

A6 ? ANY Number

A7 ? ANY Number

A8 =SUM(A1:A7) you will get total sum of above numbers on this A8 Cell which is auto sum whenever you change the value on above cell.

Formulas are used to specify calculations based on values in designated cells. Excel supports basic calculations as well as statistical, trigonometric and other specialized functions.

Formulas used in Excel must follow a certain syntax.

- All formulas begin with an equals sign
**(=)**. - Some formulas use operands such as
**+,-, *,/**for addition, subtraction, multiplication or division.

For example, the formula =A1+A2+A3 would add the contents of cells A1, A2 and A3. - Other formulas refer to different functions such as SUM, AVERAGE and others.

For example, the formula =SUM(A1:A3) would add the contents for the range A1 through A3. - Formulas can be
**combined with operands.**

For example, the formula =10*SUM(A1:A3) would add the contents cells A1 through A3 and multiply them by 10. - Functions can
**be nested within each other.**

For example, the formula =SQRT(10*SUM(A1:A3)) would take the square root of ten times the sum of cells A1 through A3. When functions are nested, it is important that the number of left parentheses match the number of right parentheses.

In the cell that you
want the result to appear in, enter the appropriate formula from the following
examples.

How to Count the Occurrences of a Number

Use this formula

=SUM(IF(range=number,1,0))

where range is the range that you want to search, and number is the number that you want to count.

NOTE: This formula must be entered as an array formula. To enter an array formula, press CTRL+SHIFT+ENTER.

How to Count the Occurrences of a Text String

Method 1

Use this formula

=SUM(IF(range="text",1,0))

where range is the range that you want to search, and text is the text that you want to find (the text must be enclosed in quotation marks).

NOTE: The above formula must be entered as an array formula. To enter an array formula, press CTRL+SHIFT+ENTER.

Method 2

Use the COUNTIF() function to count the occurrences of a text string. For example, use the formula

=COUNTIF(range,"text")

where range is the range of cells that you are evaluating, and text is the text string that you want to count instances of (note that text must be enclosed in quotation marks).

NOTE: This formula must be entered as an array formula. To enter an array formula, press CTRL+SHIFT+ENTER.

Wildcard characters can be used within the COUNTIF function.

The asterisk character (*) represents more than one character. For example, to count all the cells in the range a1:a10 that contain an "x," you can use the following formula:

=COUNTIF(a1:a10,"*x*")

The question mark character (?) can also be used to represent one wildcard character -- for example, to count all cells in the range whose second character is the letter, such as "ax" or "bx."

=COUNTIF(a1:a10,"?x*")

For example, you have three numbers from A1 to A3. On row A4, type =SUM(A1:A3).

That should do it. :)

Use the following formula as an array formula, you need to hit "Shift+Ctrl+Enter" after entering the formula. Lets say you have the Name in column "B", the Age in column "C" and the amount paid in column "D". Here is the formula.

=SUM((B2:B7="Abhilash")*(C2:C7>0)*(D2:D7))

It will calculate the amount paid if the name =Abhilash" and the Agr is greater than zero.

=SUM((B2:B7="Abhilash")*(C2:C7>0)*(D2:D7))

It will calculate the amount paid if the name =Abhilash" and the Agr is greater than zero.

Use the function =sum() to add numbers. To sum, for example, all of column A, enter in the formula bar =sum($A:$A). You can use the subtotal function within the range you are adding and the answer will not count towards the final total.

for example, cell A1 has date (01-01-2008) and cell A2 has current date (08-24-2008) and cell A3 shows total days, is that you want to know? if yes, apply formula as under...

cell A3......(properties set as General to show digits)................ =SUM(A2-A1)

cell A3......(properties set as General to show digits)................ =SUM(A2-A1)

First check the formatting of the cells, then check under file-preferences to see what works is programmed to do, if this gives no clue, you could easily create a copy to experiment on and on the copy, highlight the entire sheet, and clear all functions and formats, then experiment with your calculation, if it performs ok, you will know that there was something else going on in the original cells. Finally, instead of the auto-sum function you could manually put in the sum formula eg D2=sum ( A34:A57)

If all this fails, post back and we'll dig further......good luck

Here is one way:

In this example, my numbers are in cells a1 through a4. My average is computed with the formula:

=SUM(A1:A4)/COUNTIF(A1:A4,"<>0")

I'm summing the range of numbers and dividing that by the count of nonzero numbers. With this formula, you'll get an error if there are no nonzero numbers.

Try using the SUMIF function for one condition or multiple conditions. Use the SUMIF worksheet function to create a total value for one range based on a value in another range. For example, for every cell in the rage B5:B25 that contains the value "Northwind", the following formula calculates the total for the corresponding cells in the range F5:F25. Formula:

=sumif(B5:B25,"Northwind",F5:F25)

Here are SUMIF functions for multiple conditions.

=sum(if((B5:B25="Northwind")*(C5:C25="Western"),F5:F25))

=sum(if((B5:B25="Northwind")+(C5:C25="Western"),F5:F25))

=sum(if(B5:B25="Northwind",IF(C5:C25="Western"),1,0)))

Also check your help for SUMIF functions.
