The syntax is... sum(start:end) - where 'start' is the first cell in the range and 'end' is the last.
To get a total, which can also be called an aggregate, you should use the SUM function. You list the cell references, or the cell range with the values you want to add inside the function. Arrange the values you want to add in a column if possible. Then, suppose your values were in column B, from B2 to B20, you would do this in a blank cell:
=SUM(B2:B20)
That will total all the values in those cells. The colon indicates the range being between those two cells. If the cells are in a row, say row 3 from column B across to column K, then the formula would be like this:
=SUM(B3:K3)
If the cells are in separate cells spread around, you can create a comma separated list in the SUM function, and even include a mix of ranges and individual cells, like this:
=SUM(B4,B8,B11,D3:D10,F15)
In a spreadsheet you use the Sum function.
The syntax is... sum(start:end) - where 'start' is the first cell in the range and 'end' is the last.
You can use the =SUM function or you can go to the cell below the numbers you want to sum and click on the Auto Sum button.
The SUM function, like this: =SUM(A1:A23)
The SUM function.
Sum Function
To be technically accurate, no function does this. The answer you are looking for is the AVERAGE function. It divides by the amount of cells that have values in them, not by the amount of cells. In most situations, all of the selected cells have values in them, but there are cases when they don't.
In Excel you can use the COUNT function to count the amount of cells that have numbers in them and the COUNTA function to count cells that have any kind of data in them.
It sounds like you are asking about the SUMIF function. SUMIF adds all numbers in a range of cells, based on a given criteria.=SUMIF(range,criteria,sum_range)range = range of cells that you want to apply the criteria against.criteria = determines which cells to add.sum_range = range of cells to sum.
SUM function
The COUNTIF function can do that.
No, the range automatically selected by Excel isn't always right. Excel doesn't know what the user wants to select, but chooses what might be appropriate, like the column of numbers above a SUM function. The user can go with what Excel has chosen, or choose their own cells.
It is a function that allows you to count the amount of blank cells in a range. So if you want to count how many cells were in the range from A2 to A20, the function would be as follows: =COUNTBLANK(A2:A20)
The most basic function in Excel is SUM() Other functions are AVERAGE, MIN, MAX
It you select the blank cell under a column of numbers or a blank cell at the end of a row of numbers and hit the Autosum button it will enter the SUM function and select the cells above in the column, or to the left in a row. Pressing Alt and the = key will also do the same thing. If you select the column or the row with the numbers and click the button or do Alt and the = key, then it will also do the same.
The MODE function finds the most commonly occurring number in a range of numbers.
=SUM(X1:X10)
