In Excel, a formula is an expression that calculates the value of a cell. A function is a pre-defined formula that performs calculations using specific values, called arguments, that you provide. For example, the PMT function calculates the periodic monthly payment for a loan based on an interest rate and the number of payments. You can use functions to perform simple calculations like adding two numbers together or more complex calculations, like finding an average or determining the highest value in a range of cells. This article will teach you the basics of creating formulas and functions in Excel so that you can start taking advantage of all that this program has to offer if you want to learn excel (voorals je excel wilt leren).

Create a Formula

You can create a formula in Excel by typing it directly into a cell or by using the Function Library. To type a formula directly into a cell, begin by clicking on the cell in which you want to insert the formula. Then, type an equal sign (=) followed by the numbers or cells that you want to include in the calculation. For example, if you want to add together cells A1 and B1, you would type =A1+B1 into the cell. Once you have finished typing the formula, press Enter on your keyboard to calculate the result. 

You can also insert a formula by using the Function Library. To do this, click on the cell in which you want to insert the formula. Then, click on Insert Function (f x) from the ribbon at the top of the screen. This will open up the Function Library where you can browse through all of the available functions or search for a specific one. When you have found the function that you want to use, click on it and then click on OK. This will insert the function into your chosen cell with placeholders for each argument. Simply click on each placeholder and enter the appropriate values. When you have finished entering all of the arguments, press Enter on your keyboard to calculate the result. 

Add Numbers Together with SUM Function 

One of the most commonly used functions in Excel is SUM, which allows you to add together a range of cells. For example, if you have cells A1 through A10 that contain numeric values, you could use =SUM(A1:A10) to add all of those values together and display the result in another cell. 

Get an Average with AVERAGE Function 

Another common function that you may need to use is AVERAGE, which calculatesthe arithmetic meanof a range of cells. The arithmetic mean is simplythesumof a group of numbers divided by thenumberof items in that group. For example, if cells A1 through A5 contained numeric values 5, 10, 15, 20, and 25 respectively, then =AVERAGE(A1:A5) would calculate 20 (the sum of 5+10+15+20+25 divided by 5). 

Conclusion: 

Excel is a powerful program that can be used for everything from tracking inventory levels to creating complex financial models. And while it may seem daunting at first glance, once you understand some of the basic concepts behind formulas and functions, Excel becomes much more user-friendly. So what are you waiting for?
