This document provides an overview of key aspects of spreadsheets including what they are, their basic structure of rows and columns with cells at each intersection, and some common tabs and functions. Spreadsheets are used to record and compare numerical or financial data. The Home tab allows formatting and editing cells while the Insert tab adds items like pictures and charts. Formulas can perform calculations based on cell values and pivot tables can aggregate and restructure information.

1. An overview

2.  What is a Spreadsheet ?
 A spreadsheet, also known as a worksheet, contains rows and
columns and is used to record and compare numerical or financial
data.

3.  Each spreadsheet consists of rows and
columns.
 A cell is the intersection of a row and column.
 Rows are labeled with 1,2,3,4.....
 Columns are labeled with A,B,C,D....

4.  Home Tab
 We can format the text in your document, cut, copy, and paste information.
 We can change the alignment of data, insert, delete, and format cells.
 The Home Tab also allows us to change the number of your data (i.e. currency, time, date).
 Insert Tab
 We can insert various different things from this tab such
as pictures, clip art, charts, links, headers and footers, and word art.
 Page Layout
 Herewe are able to add margins, themes to our document, change the orientation, page
breaks, and titles.

5. A formula is a way for us to make calculations based upon
data written in the spreadsheet.
What’s best about formulas is that they are linked to the
data in such a way that if the data changes, the formula
gives an updated result, reflecting the change.
An example :-

6.  We can use : bold face, italics, underline, change the color, align
(left, right, center), font size, font, etc.
We need to select the cell (or group of cells) that we wish to change
the formatting and then go from the FORMAT menu.

7.  The VLookup function searches for value in the left-
most column of table array and returns the value in
the same row based on the index number.
The syntax for the VLookup function is:
VLookup( value, table_array, index_number, not_exact_match )

8.  The HLookup function searches for value in the top
row of table_array and returns the value in the same
column based on the index_number.
The syntax for the HLookup function is:
HLookup( value, table_array, index_number,
not_exact_match )

9.  A pivot table can aggregate your information and
show a new perspective in a few clicks. You can also
move columns to rows or vice versa.

10. That day was my first day in class.
Had access to internet , so out of mere excitement
had logged in, and i had lost the context going in
the class , i know it was very stupid of me to do
so. But all i can say is SORRY.
Such mistakes wont be repeated again.
