Basic Considerations• A spreadsheet is basically a sheet of paper
with columns and rows like you would use to keep business records.
Basic Considerations• The columns and rows form a grid. Each
column has a letter at the top and each row has a number at the side.
Basic Considerations• Where each column and row intersect is a
cell. In this picture the cursor is in cell A1.
Basic Considerations• A typical computer spreadsheet has 256 rows
identified as A through IV and 65536 rows. This gives a total of 16,777,216 cells.
• A cell contains data. Data can be– constants (numbers)– labels (such as column headings)– formulas (for calculations)
Basic Considerations• Spreadsheets are useful in a variety of
disciplines. These include:– business - for financial records– science - for data analysis and calculations– math - for graphing, formulas and statistics
• Spreadsheets are used in all disciplines where data analysis, graphs and charts are needed.
