Diving into Basic Microsoft Excel Formulas

Understanding Excel formulas is essential for successfully maneuvering through your spreadsheet tasks. Excel formulas form the backbone of data manipulation, providing a way to perform calculations and conduct analysis to reveal key insights from your data.

Common Functions Used in Excel

Excel uses inbuilt functions which can be used to create formulas. Here are some of the popular ones that you might find useful:

• SUM: This function is used to add the numerical values in a range.
• AVERAGE: This function automatically computes the average of the numbers in a set range.
• COUNT: This is used to count how many cells within a range have numbers.
• MIN and MAX: These functions give the smallest and largest numbers in a ranged set, respectively.
• IF: This function performs a logical test that returns one value if TRUE and another if FALSE.

For instance, to sum the numbers in cells B2, B3, and B4, you would use the formula \(=SUM(B2:B4)\).

How to Apply Basic Microsoft Excel Formulas

Begin inputting Microsoft Excel formulas by clicking an empty cell and type an equals sign (\("=") using the keyboard. This is Excel's way of knowing that you're going to input a formula rather than text or numbers. The syntax of a basic Excel formula is:

= FunctionName(arguments)

Where, 'FunctionName' is the name of the function used, and 'arguments' are input values or cell references on which the function will act. For instance, to use the SUM function with specific numbers or references to cells, you can either type the numbers directly or use the cell names, separated by commas

=SUM(3,5,8)
=SUM(A1,B2,C3)
=SUM(A1:A10)

The first formula would give a result of 16 calculated as \(3+5+8\). The second formula returns the sum of the contents of cells A1, B2, and C3. And the third formula adds the values in cells from A1 to A10.

Interpreting Results of Basic Microsoft Excel Formulas

Post entering a formula, pressing the Enter key on your keyboard will cause Excel to calculate the result. The result will then appear in the cell where you typed the formula. For instance, if you applied the function '=SUM(3,5,8)' in cell A1, the number '16' will show up in cell A1. However, when you click on the cell, the formula appears in the formula bar at the top of the Excel screen. This feature allows you to easily view and edit your formulas. Despite the result of the formula changing as the values in the referenced cells change, the formula itself remains constant unless edited. In the event of an error in your formula, Excel will show an error message instead of a result. These messages usually start with "#" and come with an error string that explains what kind of error occurred. For example, if you attempted to divide a number by zero in cell C1 ('=B1/A1') and cell A1 contained zero, Excel would display a "#DIV/0!" error in cell C1, alerting you of the impossibility of the calculation. By understanding these essentials of Excel formulas, you're well on your way to analyse and manipulate your data efficiently and effectively. It's time to dive in and start experimenting with formulas in Excel!
