There are a few basic Excel formulas that you should know how to use in order to make the most of the program. The SUM function, for example, can be used to add together a series of numbers. The AVERAGE function can be used to calculate the average of a series of numbers, and the MAX function can be used to find the largest number in a series. These are just a few of the most basic Excel formulas - there are many others that you can use to perform more complex calculations.
To use an Excel formula, you first need to type the = symbol followed by the name of the function that you want to use. For example, if you want to use the SUM function, you would type =SUM(). Next, you need to type the parentheses and then list the numbers that you want to add together. Finally, press the Enter key on your keyboard to calculate the result.
Here's an example: let's say you have a list of numbers in column A, and you want to find the total of all of those numbers. You would type =SUM(A1:A10) into a cell in column B, and then press the Enter key. This would calculate the total of the numbers in the range A1:A10.
