Excel Formula Language and Functions

Study Notes

Language in Excel

Formula Language

Formula language is used to perform calculations and manipulate data in Excel.
Formulas start with an equals sign (=) and can include numbers, operators, and references to cells or ranges.
Examples of formulas:
- =A1+B1 adds the values in cells A1 and B1
- =SUM(A1:A10) sums the values in cells A1 through A10

Functions

Functions are pre-built formulas that perform specific tasks.
Examples of functions:
- SUM(range) sums the values in a range of cells
- AVERAGE(range) averages the values in a range of cells
- IF(logical_test, [value_if_true], [value_if_false]) tests a condition and returns one value if true and another value if false

Text Functions

Text functions are used to manipulate and analyze text data.
Examples of text functions:
- LEN(text) returns the length of a text string
- LOWER(text) converts text to lowercase
- PROPER(text) converts text to proper case (first letter capitalized)

Error Handling

Error handling is used to manage errors that occur when formulas are calculated.
Examples of error handling functions:
- IFERROR(cell, value) returns a value if an error occurs in a cell
- IFBLANK(cell, value) returns a value if a cell is blank

Formula Language

Formulas in Excel start with an equals sign (=) and can perform calculations and data manipulation.
Formulas can include numbers, operators, and cell references or ranges.
Example: =A1+B1 calculates the sum of values in cells A1 and B1.
Example: =SUM(A1:A10) computes the sum of values from cells A1 to A10.

Functions

Functions are pre-defined formulas designed for specific tasks in Excel.
Examples include:
- SUM(range): Adds all values in a designated range of cells.
- AVERAGE(range): Calculates the average of values within a specified range.
- IF(logical_test, [value_if_true], [value_if_false]): Evaluates a condition and provides one result if true and another if false.

Text Functions

Text functions are utilized to manipulate and analyze string data in Excel.
Examples include:
- LEN(text): Returns the number of characters in a text string.
- LOWER(text): Converts all characters in a text string to lowercase.
- PROPER(text): Formats a text string to have the first letter of each word in uppercase.

Error Handling

Error handling functions are designed to manage errors arising from formula calculations in Excel.
Examples include:
- IFERROR(cell, value): Provides a specified value when an error occurs in the referenced cell.
- IFBLANK(cell, value): Returns a specified value if the referenced cell is blank.

Excel

Excel relies on formulas and functions for data manipulation and calculations.
Formulas are created using numbers, operators, and functions to derive values.
Functions are pre-defined formulas like SUM, AVERAGE, and COUNT that execute specific operations.
The syntax starts with an equal sign (=) for formulas and uses parentheses for grouping.
Arguments in functions are separated by commas to clarify input values.
Excel includes error handling features, providing messages and tools for debugging to address formula issues.

PowerPoint

PowerPoint's language involves various slide elements such as text (headings, captions), images (graphics, icons), shapes (geometric forms), and tables (data displays).
Layout and design in PowerPoint are governed by principles of alignment, which positions elements, proximity, which groups related items, and contrast, using color and font to highlight information.
Transitions and animations enhance presentations, with entrance effects for how elements appear, exit effects for disappearance, and motion paths for movement of elements across the slide.
