An Excel formula is an expression that performs a calculation in Microsoft Excel.
Here are the key characteristics and components of an Excel formula:
Starts with an equals sign (=): Every formula in Excel must begin with an equals sign.
2 This tells Excel that the following characters are a calculation, not just regular text.Example:
=A1+B1
Contains a combination of elements: Formulas are typically made up of one or more of the following:
Cell references: These point to the data in specific cells.
3 Examples:
A1
,B5
,C2:C10
(a range of cells)
Operators: These are symbols that indicate the type of calculation to perform.
4 Arithmetic operators:
+
(addition),-
(subtraction),*
(multiplication),/
(division),^
(exponentiation)5 Comparison operators:
=
(equal to),>
(greater than),<
(less than),>=
(greater than or equal to),<=
(less than or equal to),<>
(not equal to)6 Text concatenation operator:
&
(joins text strings)7
Functions: These are pre-defined calculations that perform specific tasks.
8 Excel has hundreds of built-in functions for various purposes (mathematical, statistical, logical, text, date and time, financial, etc.).9 Examples: SUM(), AVERAGE(), IF(), VLOOKUP(), TODAY()
Constants/Values: These are actual numbers or text directly entered into the formula.
Examples:
100
,"Hello"
Parentheses (): Used to control the order of operations (following the standard mathematical order of operations, PEMDAS/BODMAS). Operations within parentheses are performed first.
How Formulas Work:
When you enter a formula into a cell, Excel calculates the result and displays that result in the cell.
Why are Excel Formulas Important?
Automation: They automate calculations, saving time and reducing errors.
Dynamic Updates: If the data in the cells referenced by a formula changes, the formula automatically recalculates, updating the result.
Analysis: They allow for complex data analysis, forecasting, and "what-if" scenarios.
11 Efficiency: They make spreadsheets powerful tools for managing and understanding data.

Simple Formula Example:
Let's say you have the number 10 in cell A1 and 20 in cell B1. To add them, you would enter the following formula in another cell (e.g., C1):
=A1+B1
Excel would then display 30
in cell C1.
Total
SUM(C2:D2)
Percent(%)
=(E2/200)*100
RESULT
=IF(AND(C2>=32,D2>=32),"Pass","Fail")
DIVISION
=IF(AND(G2="Fail")," * * * ",IF(AND(F2>=60),"1st",IF(AND(F2>=45),"2nd",IF(AND(F2>=32),"3rd"))))
