Uses functions and formulas in
an electronic spread sheet tool
to perform advanced
calculations on numerical data

Objectives
• Define an electronic spread sheet.
• Identify functions and formulas found in Excel.
• Give the symbols of operations used in Excel.
• Use functions and formulas in an electronic spread
sheet tool to perform advanced calculations on
numerical data.

Let’s be informed
An electronic spread sheet application program is designed to perform
basic mathematical and arithmetic operations. MS Excel is one example
of the most commonly used computerized worksheets. It is widely used in
accounting and financial applications, statistics, statistics, engineering
calculations, as well as in analyzing data.

Let’s be informed
Spread sheets are designed with functions and formulas that will make
calculating numerical data easier and convenient for you. Using formulas
and functions will help you increase the accuracy of your calculations
while decreasing the amount of time you need to spend in Excel.

Let’s be informed
Functions are calculations that return a result. To create and enter
functions, always start with an equal sign (=). Without it, Excel will not
calculate a result. The inputs in functions are called arguments.
Arguments can be in a form of numbers, cell references, or texts.

Let’s be informed
There are hundreds of functions found in Excel. All these can be accessed
using either of the following methods:
Click the Insert Function button-
f from the left side
of formulas tab. Or use the
keyboard short cut ALT+M+F

Let’s be informed
There are plenty of pre-set
formulas that you can use in
excel

Let’s be informed
Let us Choose “STATISTICAL”
Then “AVERAGE”
But first you need to have a data in you excel

Let’s be informed
But first you need to have a data in you excel
Let’s say you are going to get
Your average in your 5 quizzes.
Cell A1 -Title
Cell A2-A6 –Quiz 1 to 5
Cell B2-B6 -Grades in each quizzes
Average will be in Cell B7

Let’s be informed
If you follow the steps this will show in your screen

Let’s be informed
If you follow the steps this will show in your screen
If you click OK you will get the average in cell B7

Let’s be informed
Note:
A,B,C,D,……are the column in your excel
123456789….are the rows in your excel

MS Excel Chart
A chart is a visual representation of data in worksheet of the spread sheet
program. It makes it easy to study and interpret data.
Symbol Operation Example Purpose
+ Addition = A1 + B2 It adds the values
of c ell A1 and B2
- Subtrac tion + A1 – B2 It subtrac ts the
values of Cell A1
and B2
* Multiplication = A1 * B2 It multiplies the
values of c ell A1
and B2
/ Division = A1/ B2 It divides the
values of c ell A1
and B2

MS Excel
There are different categories of functions. Some of which are the
following:
• Mathematical. These include mathematical functional such as
AVERAGE(), SUM(), etc.
• Date and Time. These are concerned with the date and time such as
DATEVALUE() that converts dates written in texts to numbers.
• Logical. These are used whether arguments, texts, or values are true or
not depending on the set standard.
• Look up Reference. These functions are used when looking for an entry
or value in the spread sheet.

MS Excel
Below are some examples of the commonly used functions:
SUM This is used to add two or more numbers together. Cell
references are used in this formula.
Separate numbers or c ell references by commas then it will
automatically be added.
Example = SUM(9, 14) or = SUM(A1, B3) or SUM(A@:C9)
For range of c ells, separate them with a colon.
Example: = SUM(A2:C9)
AVERAGE This is used to c alculate average of a series of numbers.
Example = AVERAGE(A1:A10)
COUNT This is used to c ount the number of c ells in a range that have
numbers in them. For instance, if there are five c ells that c ontain
numbers in A1 to A 15, then the result is 5.
Example = COUNT(A1:A15)
COUNT This is used to c ount the number of c ells that have numbers
and/ or any other c harac ters in them. It works with all data types.
LEA This is used to return the length or a string or an entry.
Example = LEN(entrepreneurship) is 16

MS Excel
Formulas, on the other hand, are combinations of functions, operands,
and operators. These are used when you are manually calculating. For
example, you could put your hanging organizer budget into a formula
like this:
Remaining cash = total cost of materials – labor
Input the formula in Excel:
= 82-30, then press Enter. The answer is 52, which is the remaining cash
for your hanging organizer project.

Let’s Answer
1. What is an electronic spread sheet
application program?
2. Differentiate functions from formulas.
3. Explain the different categories of functions.
4. Give examples of commonly used functions.

Let’s Remember
• The electronic spread sheet software is used to create
and produce calculated data needed by individuals and
businesses.
• The spread sheet is designed with functions and
formulas that will make calculating numerical data easier
and convenient for you.
• An Excel functions always begins with an equal (=)
sign. Formulas on the other hand, are used like when you
are manually calculating.

Let’s Do Together
A. Create an Excel file for the expenses below. Using the formulas and
functions discussed calculate the following:
1. = SUM (total cost of ingredients used)
2. = COUNT (total number of materials used)
Marketing
Budget
Expenses
Allowance 700.00
Item Bought Quantity Cost/ Unit Total
Chicken 1 ½ kg 150/ kg
Tilapia 1 kg 140/ kg
Assorted
Vegetables
½ kg 120/ kg
Garlic ¼ kg 80/ kg
Eggs 1/ 2 6.50.00/ each
Total
Expenses
Balance
Expenses
(Allowance
minus Total
Expenses

Let’s Do Together
B. Write True on the line if the statement is correct and False if it is not.
_________ 1. The COUNT is used to calculate the number of cells in a range that
have numbers in them.
_________ 2. There are only four functions in MS Excel.
_________ 3. The LEN formula counts the number of characters in a cell.
_________ 4. Functions are combinations of functions, operands, and operators.
_________ 5. Average is used to add two or more numbers together.
_________ 6. Formulas always start with an equal sign.
_________ 7. Without an equal sign, Excel will not calculate a result.

Assignment

Chicken
Sandwich
34,000.00 43,700.00 23,000.00
Egg Sandwich 39,450.00 25,000.00 31,900.00
Fries 23,000.00 32,000.00 35,000.00
Softdrinks 16,800.00 24,000.00 33,800.00
