Formulas in Excel
Formula Basics
- A formula in Excel is an expression that calculates a value based on values in other cells.
- Formulas can be used to perform arithmetic, comparison, and logical operations.
- Formulas can be entered into a cell using the
=sign, followed by the formula.
Formula Types
- Arithmetic formulas: Perform mathematical operations such as addition, subtraction, multiplication, and division.
-
Comparison formulas: Compare values in cells, such as
=A1=B1to check if the values in cells A1 and B1 are equal. - Logical formulas: Use logical operators such as AND, OR, and NOT to evaluate conditions.
- Text formulas: Manipulate text strings, such as concatenating strings or extracting substrings.
Formula Operators
-
Arithmetic operators:
-
+(addition) -
-(subtraction) -
*(multiplication) -
/(division) -
^(exponentiation)
-
-
Comparison operators:
-
=(equal to) -
<>(not equal to) -
>(greater than) -
<(less than) -
>=(greater than or equal to) -
<=(less than or equal to)
-
-
Logical operators:
-
AND(logical and) -
OR(logical or) -
NOT(logical not)
-
Formula References
-
Cell references: Refer to a specific cell or range of cells, such as
A1orA1:B2. -
Named ranges: Refer to a named range of cells, such as
SalesData. -
Absolute references: Refer to a cell or range of cells using an absolute reference, such as
$A$1.
Formula Errors
- #NAME?: The formula contains a reference to a named range that does not exist.
- #VALUE!: The formula contains a value that is not a valid number.
- #REF!: The formula contains a reference to a cell that does not exist.
- #DIV/0!: The formula attempts to divide by zero.
- #N/A: The formula contains a reference to a value that is not available.
