If you have a number in Cell A2 (say 100), and you put the amount of percentage increase or decrease in Cell A3 (say -10%), then put this formula into Cell A4 to calculate the answer:

=A2*(1+A3) , which then shows as the answer (90).

=A2*(1+A3) , which then shows as the answer (90).

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.

Let say you have table like this

' A ' B

---'--------------'-----------

1 ' First ' 2

2 ' Second ' 1

3 ' Third ' 3

On Cell C1 or other cell you like, try to type this formula

=IF(B1<B2;IF(B2<B3;A1;IF(B1<B3;A1;A3));IF(B2<B3;A2;A3))

That's all, just IF and math operand

' A ' B

---'--------------'-----------

1 ' First ' 2

2 ' Second ' 1

3 ' Third ' 3

On Cell C1 or other cell you like, try to type this formula

=IF(B1<B2;IF(B2<B3;A1;IF(B1<B3;A1;A3));IF(B2<B3;A2;A3))

That's all, just IF and math operand

I assume you mean Fibonnaci series.

Use Excel.

In cell A1, type 0 (that's zero)

In cell A2, type 1

In cell A3, type +a1+a2

Copy cell A3 down to as many "A" cells as you like.

Read the results.

Open excel and do the following...

A1:**Weekly Entry** B1: **Weekly loss** C1:**Total loss**

A2: Enter pound B2: Nothing Yet C2: Nothing Yet

A3: Enter pound B3:=if(a3="","",a2-a3) C3: =if(a3="",'',b3-b2)

Last thing you need to do is copy the cells A3,B3, and C3 and paste to the next row for every week.

The formula for A1 is: =SUM(B4,B5)

A2 is: =SUM(C4,C5)

A3 is: =SUM(A1:A2)

To test this, put 25 in cell B4, 25 in cell B5, then 30 in cell C4, and 30 in cell C5.....the result in cell A3 is 110.

Hope this helps.
