C. Spreadsheet Work Area: By default the work area is a grid. Along the top are column headers A through Z (and beyond), and along the left side are numbered row headers. Each rectangle in the spreadsheet is called a cell, and they are each named according to their column letter and row number. For example, the cell selected here is A3.
B. This section lets you insert visual elements, like picture files, pre_built shapes, and SmartArt. You can add shapes and resize, recolor, and reposition them to create intuitive data sets and reports. SmartArt objects are prebuilt diagrams that you can insert text and information into. Theyre great for representing what the data says in another place on your workbook.
The Clear button lets you either clear the value, or just clear cell formatting.
B. These are print options. You can change the margin for printing, whether you want a vertical or horizontal print alignment, which cells in your sheet you want to print, where youd like page breaks, and whether it has a background (to place your company name, for example). You can also start giving each page a heading using the Print Titles button, and the order to print each section.
