How to do calculations in excel
Microsoft Excel is a powerful spreadsheet tool that helps users manage, analyze, and present data effectively. One of its most valuable features is the ability to perform calculations using formulas and functions. In this article, we’ll guide you through the process of performing calculations in Excel step by step.
1. Basic calculations
To begin, let’s explore some basic calculations you can perform in Excel:
a) Addition
Enter the values you’d like to add into two or more cells, then click on an empty cell where you want the sum to appear. Type “=A1+A2” (substitute the cell references accordingly) and press Enter.
b) Subtraction
Just like with addition, enter your values into two cells and click on an empty cell for the result. Type “=A1-A2” and press Enter.
c) Multiplication
Use “* “to multiply values: “=A1*A2.”
d) Division
Use “/ “to divide values: “=A1/A2.”
You can also combine multiple operations in one formula by using parentheses for a proper order of execution.
2. Using functions
Excel comes with a vast library of built-in functions that make complex calculations easier. Some commonly used functions include:
a) SUM: Adds up a range of cells.
Use “=SUM(A1:A10)” to return the sum of cells A1 through A10.
b) AVERAGE: Returns the average value of a set of numbers.
Use “=AVERAGE(A1:A5)” to find the average of cells A1 through A5.
c) MAX: Returns the highest number in a range.
Use “=MAX(B1:B6)” to find the highest value in B1 through B6.
d) MIN: Returns the lowest number in a range.
Use “=MIN(C3:C8)” to find the lowest value in C3 through C8.
3. Absolute and relative references
In Excel, cell references can be either relative or absolute. When using relative references, Excel adjusts the formula if you copy or move it to another cell. This feature is helpful when applying the same calculation across multiple rows or columns.
However, sometimes you may want to keep a reference constant, which is where absolute references come into play. To make a cell reference absolute, use a “$” symbol before the row number, the column letter, or both (e.g., $A$1).
4. Using multiple sheets
If your data spans across multiple sheets, you can still perform calculations by referencing cells in other sheets.
a) Click on an empty cell where you’d like the result to appear.
b) Type “=” followed by the name of the sheet you’d like to reference enclosed in single quotes (e.g., ‘=Sheet2’).
c) Add an exclamation mark “!” after the sheet name and then type your desired formula (e.g., ‘=Sheet2!A1+A2’).
In conclusion, Microsoft Excel offers various options for performing calculations with ease. By mastering basic operations, using functions, and understanding relative and absolute references, you’ll be well-equipped to tackle any task at hand using this versatile software.
