I also changed the value in A9 to the text string hello to show the difference. Here I have entered the COUNT function into D2 and the COUNTA function into E2, using A2:A12 range as the data set for both functions. Let’s start with the COUNT and COUNTA functions. Using the same set of data, we’re going to use the rest of the summary functions to see what kind of numbers we can calculate. This was a very basic overview of how to use functions and formulas in Excel, but it’s enough so that you can start using all of the data summation functions. You could even type something like =SUM(A1:B12) and it will sum all values in A1 thru A12 and B1 thru B12. To sum A1 to A12, all we have to do is type =SUM(A1:A12) with a colon separating the two cell references instead of a comma. Let’s say we wanted to sum up all the values from A1 to A12, then how would we go about it? We could type something like =SUM(A1, A2, A3, etc), but that is very time consuming.

There is also another way to use SUM that explains another concept behind arguments in Excel. Instead, you’ll see A2+B2, A3+B3 and so on. Drag the cursor down to the last row with the data and then let go at the end.Įxcel is smart enough to know that the formula should change and reflect the values in the other rows rather than just showing you the same A1 + B1 all the way down. Now click and hold your mouse button down. Move your mouse cursor to the bottom right corner of cell D1 and you’ll notice it changes from a white cross to a black plus sign. So we summed one row together, but how can we sum all the other rows without typing the formula again or copying and pasting? Luckily, Excel makes this easy. Excel will also highlight the cell in the same color as the cell reference so you can see the corresponding values exactly. Secondly, either you can type in the cell reference manually (A1) or you can click on the cell A1 after you typed the open parenthesis.

This particular function can take an infinite number of values since that is how the SUM function works. In our example, it shows number1, number2, etc. Firstly, you’ll notice that when you type the first opening parenthesis ( after the function name, Excel will automatically tell you what arguments that function takes. There are a couple of things to note while typing a formula in Excel. You should see the result is simply the value of A1 + B1.

Go ahead and type random numbers from A1 to A10 and B1 to B10 for our data set. Easy enough right?īefore we write our new formula, let’s add some data in columns A and B to work with. A1 is the first cell on the spreadsheet at the top left. Every row has a number and every column has a letter. How do we reference a cell inside the Excel formula? Well, that’s pretty easy.
