Study Notes
Formulas in Microsoft Excel
Formula Basics
- A formula is an expression that calculates a value from values in other cells
- Formulas begin with an equal sign (=) followed by a calculation
- Example:
=A1+A2adds the values in cells A1 and A2
Formula Types
- Arithmetic formulas: perform mathematical operations (e.g., +, -, *, /, %)
- Comparison formulas: compare values (e.g., =, <, >, <=, >=)
- Logical formulas: evaluate true or false conditions (e.g., IF, AND, OR)
- Text formulas: manipulate text strings (e.g., LEN, LOWER, UPPER)
- Date and time formulas: work with dates and times (e.g., TODAY, NOW, EOMONTH)
Formula Operators
-
Arithmetic operators:
-
+(addition) -
-(subtraction) -
*(multiplication) -
/(division) -
%(modulus)
-
-
Comparison operators:
-
=(equal to) -
<>(not equal to) -
<(less than) -
>(greater than) -
<=(less than or equal to) -
>=(greater than or equal to)
-
-
Logical operators:
-
AND(logical and) -
OR(logical or) -
NOT(logical not)
-
Formula Errors
- #NAME?: formula contains a typo or unknown name
- #VALUE!: formula contains a value that is not a number
- #REF!: formula references a cell that does not exist
- #DIV/0!: formula attempts to divide by zero
- #N/A: formula contains an invalid argument or function
Formula Tips
- Use absolute references (
$A$1) to lock cell references - Use relative references (
A1) to allow formulas to adjust when copied - Use named ranges or references to make formulas more readable
- Use the F2 key to edit a formula without leaving the cell
Formula Basics
- Formulas in Microsoft Excel begin with an equal sign (=) followed by a calculation, such as
=A1+A2, which adds the values in cells A1 and A2.
Formula Types
- Arithmetic formulas perform mathematical operations like addition, subtraction, multiplication, division, and modulus.
- Comparison formulas compare values using operators like equal to, not equal to, greater than, and less than.
- Logical formulas evaluate true or false conditions using functions like IF, AND, OR, and NOT.
- Text formulas manipulate text strings using functions like LEN, LOWER, UPPER, and more.
- Date and time formulas work with dates and times using functions like TODAY, NOW, EOMONTH, and more.
Formula Operators
- Arithmetic operators include + for addition, - for subtraction, * for multiplication, / for division, and % for modulus.
- Comparison operators include = for equal to,
for not equal to,for greater than, `` for greater than or equal to, and more. - Logical operators include AND for logical and, OR for logical or, and NOT for logical not.
Formula Errors
- #NAME? errors occur when a formula contains a typo or unknown name.
- #VALUE! errors occur when a formula contains a value that is not a number.
- #REF! errors occur when a formula references a cell that does not exist.
- #DIV/0! errors occur when a formula attempts to divide by zero.
- #N/A errors occur when a formula contains an invalid argument or function.
Formula Tips
- Use absolute references (AAA1) to lock cell references and prevent them from changing when the formula is copied.
- Use relative references (A1) to allow formulas to adjust when copied.
- Use named ranges or references to make formulas more readable and easier to maintain.
- Press the F2 key to edit a formula without leaving the cell.
