Excel: Your Go-To Tool for Crunching Numbers – How do I do calculations in Excel?

When it comes to crunching numbers and performing complex calculations, one tool stands out from the rest – Excel. This powerful spreadsheet software is an essential companion for any data-driven individual or business professional. Whether you are a finance guru, a project manager, or just someone trying to keep track of your personal expenses, Excel has got you covered.

Excel’s ability to handle large amounts of data and perform intricate calculations with ease makes it a game-changer in the world of number-crunching. With its vast array of functions and formulas, there’s virtually no mathematical problem that Excel can’t solve. But how exactly does one go about harnessing its full potential? Here, we’ll dive into the world of Excel calculations and explore some tips and tricks to help you become an expert number cruncher.

Understanding Formulas and Functions

At the heart of Excel’s calculation prowess lies its ability to process formulas and functions. Don’t worry if these terms sound intimidating at first – they are simply the building blocks that make Excel such a formidable tool.


A formula in Excel is an equation that performs mathematical operations on values within cells. It starts with an equal sign (=) followed by a combination of numbers, cell references, operators, and functions. Here’s an example:

= A1 + B1

In this formula, A1 and B1 refer to specific cells containing numerical values. The plus sign (+) acts as the operator instructing Excel to add those two values together.


Functions are predefined formulas built into Excel that simplify more complex calculations by providing ready-made instructions for specific tasks. They take arguments (inputs) enclosed in parentheses () and return results based on those arguments.

For instance:

= SUM(A1:A10)

The SUM function adds up all the values within the range A1 to A10. It saves you from manually typing out each cell reference and performs the calculation instantaneously.

Basic Mathematical Operations

Now that we have a grasp of formulas and functions, let’s start with some basic mathematical operations you can perform in Excel. Whether you need to add numbers, subtract figures, multiply quantities, or divide values, Excel has got your back.


To add two or more numbers in Excel, simply use the plus sign (+) as the operator within a formula. For example:

= 5 + 3
= A1 + B1

The first formula returns the result 8 (5 + 3), while the second formula adds up the values in cells A1 and B1.


Subtracting numbers works similarly to addition but using a minus sign (-) instead. Consider these examples:

= 7 - 2
= C2 - D2

The first formula returns the value 5 (7 – 2), while the second formula subtracts D2 from C2.

– Use parentheses if you want to change priority – otherwise calculations are performed left-to-right.
– You can also use negative numbers directly by typing a minus sign before them.

Q: How do I add numbers in Excel?
A: To add numbers in Excel, simply select the cell where you want the result to appear, type “=SUM(” and then select the range of cells you want to add. Press Enter, and Excel will calculate the sum for you.

Q: Can I subtract values in Excel? If yes, how?
A: Yes, you can subtract values in Excel. To do this, select a cell where you want the result to be displayed and type “=” followed by the value or cell reference from which you want to subtract another value or cell reference. For example, “=A1-B1”. Press Enter to get your subtraction result.

Q: How can I multiply numbers using Excel?
A: Multiplying numbers in Excel is easy. Just select a cell where you wish to see the product and use the formula “=MULTIPLY(” followed by the first number or cell reference “” second number or cell reference. Press Enter after typing it all out, and your multiplication will be done.

Q: Is it possible to divide values with Excel’s help?
A: Absolutely! Dividing values using Excel is straightforward. Select a cell where you desire your quotient to appear. Type “=” followed by either a direct value (for example, 10) or a reference (like A1) divided by (“/”) another direct value/reference. Hit Enter key and there’s your division calculation!

Q: Can I perform complex calculations like exponentiation in Microsoft Excel?
A: Yes! Microsoft Excel allows complex calculations like exponentiation too. Simply choose a target cell for displaying results and enter “=POW(” followed by either a constant/value/cell-reference as base “^” an exponent constant/value/cell-reference (e. g. , =POW(2^3)). Pressing Enter finalizes your exponentiation calculation.

Q: In excel, how can I calculate the average of a range of numbers?
A: Calculating the average of a range in Excel is effortless. Select a cell for displaying the average result and type “=AVERAGE(” followed by the cells/range you want to include (e. g. , =AVERAGE(A1:A10)). Press Enter, and Excel will compute the average for you.
