SUM function
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.
The most basic function in Excel is SUM() Other functions are AVERAGE, MIN, MAX
=SUM(range) or=SUBTOTAL(9,range)
=SUM(A1:A15) If this SUM formula is put into cell A16, then the numbers in the cells above (A1 to A15) will be shown in cell A16 as a total.
If you mean Excel, you always need a formula; there is no way around that. As a shortcut to adding numbers individually, you can use the SUM() function. Within the parentheses, you can write a range, for example: =SUM(A1:A4) This is a function but it is still also a formula. You may have confused the two things. All functions in use are in formulas and you can have formulas that have no functions.
AutoSum
Autosum allows you to automatically insert the SUM function into a cell. It will then also automatically select a group of cells to add if there are cells with numbers in them nearby. If you do it at the bottom of a column of numbers, it will automatically select the ones above to sum and if you put it at the end of a row of numbers, it will automatically select the numbers in that row to sum. You still have the option of choosing a different range of cells to sum. Autosum also gives you the option to do other common operations such as MAX, MIN, AVERAGE, COUNT and COUNTA instead of using SUM.SUM is the total of a range of numbers.EXAMPLE:=SUM(A1:A12) [Adds all of the numbers in cells A1 through A12.]
SUM [ =SUM(A1:A23) ]
