It depends which spreadsheet package you're using, and how its syntax is set but - something like... D3=A3-B3 or D3=sum(A3-B3)
a3 + b3
a3 + b3 = (a + b)(a2 - ab + b2) a3 - b3 = (a - b)(a2 + ab + b2)
kutta
a3 + b3 = (a + b)(a2 - ab + b2)
There following two options should work:=sum(A1:A3) or=A1+A2+A3
There following two options should work:=sum(A1:A3) or=A1+A2+A3
There following two options should work:=sum(A1:A3) or=A1+A2+A3
I assume you mean the formula as used in a spreadsheet? Place the formula in cell A4 =SUM(A1:A3) or you can use =Sum(A1+A2+A3) - This is a loger way of doing it but for someone new to calculations in spreadsheet cells its easier to check and edit if you need to change a cell reference.

You would use a formula such as ... =sum(a3/10) or =sum(b12*a3)
To add the 3 cells and divide the total by 3, you could do it several ways: =(A1+A2+A3)/3 =SUM(A1:A3)/3 =SUM(A1,A2,A3)/3
Excel formulas that will find the average of cells A1, A2, and A4 are: =AVERAGE(A1 ,A2, A4) or =AVERAGE(A1:A2, A4)
While there are many ways of doing it, the simplest way is to use the SUM function and a range in it like this: =SUM(A1:A5)
Using cells a3, b3 & c3 as examples...Adding a fixed number to a cell... in c3 you would use the formula =sum(a3+20)Adding the contents of two cells together... in c3, enter the formula =sum(a3+b3)
The values in cells A2, A3 & A4 will be added together - and the result displayed in the cell that contains the 'sum' formula.
=IF(A1+A2=A3,"True","False") As an example: put this LibreOffice Calc formula into A4. Type a number in A1 and also in A2, and type the answer to the sum in A3. If the answer in A3 is correct, then "True" will appear in A4 and, if wrong "False" will appear in A4.
