The proper way is:
=SUM(A1:B1)
Though you would hardly ever see any of them, it could also be done in these ways:
=SUM(A1,B1)
=SUM(A1+B1)
The most basic function in Excel is SUM() Other functions are AVERAGE, MIN, MAX
SUM() is a function within Excel which adds up the values of the cells that are passed to it. You can pass individual cells, a list of cells or a range of cells. e.g.=SUM(A1) returns the same value as the cell A1=SUM(A1,B2) return the sum of A1 + B2=SUM(A1:B2) returns the sum of the range A1:B2Ranges are effective squares of cells, so the range A1:B2 is a small 2x2 square consisting of A1, A2, B1 and B2.
Excel formulas that will find the average of cells A1, A2, and A4 are: =AVERAGE(A1 ,A2, A4) or =AVERAGE(A1:A2, A4)
Basically you can either add values individually, including cells: = 1 + 2 + 3 or, to add values in cells: = A1 + A2 + A3 Or, you can add a range of numbers, stored in adjacent cells, with the sum() function: = SUM(A1:A10)
Enter =sum(A1:A20) in the cell that you would like to display the sum, where A1:A20 is the range of cells you would like to add.
SUM function is use to aggregate in MS Excel Suppose you want to sum values from A1 to A10 in A11, type = SUM(A1:A10)
If the function allows multiple arguement, you can use another function within most functions. EXAMPLE: =IF(SUM(A1:A14)>120,SUM(A1:A14),"Oops! not enough")
SUM - If you want to add the values of cells A1 through A23, use =SUM(A1:A23).
Equations perform some type of operation.EXAMPLE:Find the sum of all numbers in the cells A1 through A23.The formula is =SUM(A1:A23)
The alphanumeric values will already be ignored during a calculation in Excel sheet. So, any formula works. For example, if you got to take out the sum of cells A1 to F1, write =SUM(A1:F1).
If you have numbers on two worksheets in cells A1:C23, you can use the formula:=SUM(sheet1!A1:sheet1!C23)+SUM(sheet2!A1:sheet2!C23)
A formula in Microsoft excel is like a formula in real life, like a math equation or math problem (ie. 2+2=4). You write the Excel formula like this: =2+2Actually it is more like =A1+A2 Or =SUM(A1:D2)The SUM is a Function the A1 -> D2 is The RangeAnd the : is the argument. When you have =SUM(A1:D2)you are adding the cell from A1 -> D2 so you are adding them together
