This document discusses formulas and functions in Excel. It defines formulas as mathematical expressions that perform calculations using values, cell references, and operators. Functions are predefined Excel formulas that can quickly perform common tasks like summing or averaging ranges of cells. Examples of commonly used functions include SUM, AVERAGE, MAX, MIN, and COUNT. The document also distinguishes between contiguous and non-contiguous cell ranges and identifies common symbols used in formulas like exponents, parentheses, multiplication, and more.

2. FORMULA
• Is a mathematical
expression which
consists of a series of
values, cell
references, and
mathematical
operators that results
in a calculation.
FUNCTIONS
• Built-in formulas in
Excel that you can
use as a quick way of
performing a task that
would usually take
more time if a formula
were used.

3. EXAMPLES OF FORMULA
=8^2
=A3*5
=2*3.1416/(B2+2)
=(1/3)*(A1-B1)/C1

4. COMMONLY USED EXCEL FUNCTIONS ∑
Function name Description Syntax
SUM Displays the sum of the range =SUM(range)
AVERAGE Displays the average value of the
range
=AVERAGE(range)
MAX Determines the LARGEST value in
the range
=MAX(range)
MIN Determines the SMALLEST value
in the range
=MIN(range)
COUNT Calculates the number of values in
the range
=COUNT(range)

5. RANGE
CONTIGUOUS
RANGE
• Range of adjacent cells
NON-CONTIGUOUS
RANGE
• Range of non-adjacent
cells
