Spreadsheet Software  What Is a Spreadsheet, and How Does It Work? A spreadsheet program allows users to perform simple and complex sorting. It also allows users to perform calculations on values entered into the program. These values can then be analyzed, graphed, and printed.

 Example: Imagine that you are in charge of a school store, and you have to prepare monthly reports on its sales. Your original data might looks as follows: Spreadsheet Software

 You might decide to use your spreadsheet to enter formulas so that the software will automatically do the following: calculate the totals for you identify the category with the highest sales and the category with the lowest sales calculate the average sales for each month  You could then use this information to create a pie chart that shows the percentage of sales for each category.

Spreadsheet Software  The Spreadsheet Screen A spreadsheet is used to organize data into cells. The spreadsheet workbook/notebook is the file in which you create and work on your data. It consists of numerous worksheets, or spreadsheet pages, each of which consists of a grid of vertical columns and horizontal rows.

Spreadsheet Software  An alphabetical letter identifies each column, and a number identifies each row.  The location where each column and row intersect is called a cell and is identified by a cell address. Example, where column C crosses row 2, the cell address is C2.  If you select several cells: A cell range is a group of cells.

Spreadsheet Software  Information entered into a spreadsheet cell is one of three types: labels, values, or formulas.

Spreadsheet Software  Labels: refer to the text information (all the words) used to describe the data in the spreadsheet. Numbers on the screen are relatively useless without some information to help users understand what the numbers mean. Labels can include the title of your worksheet, column headings, row identifiers, or words to describe the functions you have programmed the spreadsheet to perform (e.g., Total).

Spreadsheet Software  Values:  Any numerical data that will be used in calculations on a worksheet is called a value.  After the data is entered, you can format the cells as a type of number, date, or time.

Spreadsheet Software  Formulas: The real power of a spreadsheet comes from the formulas you enter into cells. A formula is a written set of instructions telling the program to perform calculations on the values you have entered.

Spreadsheet Software  All formulas begin with an indicator such as an = sign.  The order of the elements or parts of a formula is known as the syntax. Formulas follow the order of operations learned in your mathematics classes—brackets, exponents, division and multiplication (in the order they occur), and addition and subtraction (in the order they occur).  BEDMAS  In addition, spreadsheet formulas can include numbers, cell addresses, or cell ranges (e.g., B5..E9).  Benefit of using formulas: Saves time when you change values.  When you enter a new value, the formulas will automatically recalculate the answers.
