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*")

#VALUE? is an error indication meaning that Excel can't process the formula. It is most likely the result of a bad cell reference in your formula, for example, you may be trying to perform mathematical operations on a cell that contains non-numeric text data.

Yes you can create the formula outside the cell or you can create it one time and copy it down to the other cells. That way it will populate once it is used.

The formula should be Base Rate * .05 to get the result then add the result back to the base rate.

Hello ycool11,
If your asking what i think you are the formula would be

=(a2-a1)*24

That assumes a2 is that last date entered and a1 is the initial starting date. if you would like a more intense formula let me know and i'm sure i can help.

Hi Griffnz,

Your "known Y's" or 'values' are in Column B. This is the first array in the Trend formula.

Your "known X's" or 'months' are in Column A. This is the second array in the trend formula.

The trend formula is supposed to give you a projection of what the rest of the values in Column B will be over the next few months (usually continuing cells in Column A). The cells you want these values to show up in represent the third array in the formula.

Thus, your formula should look more like: '=trend(B3:B14,A3:A14,A15:A18)'

However, your formula is leaving out The values in B and adding values from C - -- but there ARE no values in C. Apparently, C is where you want the values to appear. In that case, the C array would be the third array in your formula. This would look more like '=trend(B3:B14,A3:A14,C3:C14)

If this doesn't make sense, let me know.

Are you looking to solve any particular problem?--- because there are a huge number of possible formulas in Excel.

However, in my opinion, the most commonly needed ones are addition, subtraction, division, multiplication, and summing.

Suppose you have the following numbers typed into your Excel spreadsheet:

**columns: A B C D**

**rows**

**1 ** 20 3

**2 ** 10 4

**3 ** 15 2

**4 ** 1 2 3

Then suppose you type in the following formulas (in the D column):

**columns: A B C D**

**rows**

**1 ** 20 3 =A1+B1

**2 ** 10 4 =A2-B2

**3 ** 15 2 =A3*B2

**4 ** 1 2 3 =sum(A4:C4)

Then the following answers will appear in the D column:

**columns: A B C D**

**rows**

**1 ** 20 3 23

**2 ** 10 4 6

**3** 15 2 30

**4** 1 2 3 6

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)

Okay, here's a possible solution--based on my interpretation of your problem.

Suppose you have some value in cell B1, and the month (either Jan, Feb, or Mar) is stored in cell A1. The formula in C1, which performs calculations based on which month appears in A1, is as follows:

=IF(A1="Jan",B1*0.25,IF(A1="Feb",B1*0.3,IF(A1="Mar",B1*0.4)))

In this example, the value in B1 is multiplied by .25 if the month is Jan, by .3 if it's Feb, and .4 if it's Mar.
