Excel Formulas: Arithmetic, Comparison, and Logical

Formulas in Excel

What are Formulas in Excel?

• A formula is an expression that calculates a value from values in other cells.
• Formulas are used to perform arithmetic, comparative, logical, and other operations in Excel.

Types of Formulas

• Arithmetic Formulas: Perform mathematical operations, such as addition, subtraction, multiplication, and division.
• Comparison Formulas: Compare values in cells, such as equality, inequality, and greater than/less than.
• Logical Formulas: Evaluate conditions, such as AND, OR, and NOT.
• Text Formulas: Manipulate text strings, such as concatenation and substring extraction.

Formula Basics

• Syntax: Formulas start with an equals sign (=) and are followed by the formula expression.
• Cell References: Addresses of cells or ranges of cells used in formulas.
• Operators: Symbols used to perform operations, such as +, -, *, /, >, <, =, etc.

Formula Examples

• Simple Arithmetic: =A1+B1 adds the values in cells A1 and B1.
• Comparison: =A1>B1 checks if the value in cell A1 is greater than the value in cell B1.
• Logical: =AND(A1>10, B1>10) checks if both values in cells A1 and B1 are greater than 10.
• Text: =CONCATENATE(A1, " ", B1) concatenates the values in cells A1 and B1 with a space in between.

Formula Errors

• #NAME?: Occurs when a formula uses an undefined name or range.
• #VALUE!: Occurs when a formula uses an invalid value or data type.
• #REF!: Occurs when a formula references a cell that does not exist.
• #DIV/0!: Occurs when a formula attempts to divide by zero.
