A colon would be between the two cell references that make a range like in these:
=SUM(B2:B10)
=AVERAGE(V20:X23)
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.
You use the COUNT function. Say your range was the cells for A2 to A20. In another cell you would enter the following function:=COUNT(A2:A20)You use the COUNT function. Say your range was the cells for A2 to A20. In another cell you would enter the following function:=COUNT(A2:A20)You use the COUNT function. Say your range was the cells for A2 to A20. In another cell you would enter the following function:=COUNT(A2:A20)You use the COUNT function. Say your range was the cells for A2 to A20. In another cell you would enter the following function:=COUNT(A2:A20)You use the COUNT function. Say your range was the cells for A2 to A20. In another cell you would enter the following function:=COUNT(A2:A20)You use the COUNT function. Say your range was the cells for A2 to A20. In another cell you would enter the following function:=COUNT(A2:A20)You use the COUNT function. Say your range was the cells for A2 to A20. In another cell you would enter the following function:=COUNT(A2:A20)You use the COUNT function. Say your range was the cells for A2 to A20.

Range finder. Double clicking on the formula activates the range finder and you can see what cells are in the formula. This can help you see if the correct cells are in the formula.
SUM
A function is a pre-written or built-in formula in Excel. There are many of them, all designed to do very specific tasks. The SUM function is one of the most common, making it easy to add a range of cells. See the related question below.
SUM function
A function is a pre-defined formula that is built into the spreadsheet program and can be used as a formula or as part of a formula. There are many such functions, the most commonly used one being the SUM function, which allows you to quickly add up values in a range of cells. To add all the values from all the cells from cell A1 to A15 would be done with the SUM function in a formula like this:=SUM(A1:A15)See related links for more information.

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.
A range can be one of the arguments in a function. It can also be an array of values. It depends on the function and what it needs to work.
