Introduction to Excel
Excel cells are like many calculators arranged in a grid. Each cell is capable of making mathematical calculations. The calculation can be one such as 1 + 3 or a calculation using values in other cells in the spreadsheet. Referring to other cells requires knowing how Excel refers to cells. A spreadsheet is an address grid with the grid consisting of:
Columns labeled by letters A, B, C,… X, Y, Z, AA, AB, AC,…AX, AY, AZ, BA, BB,…IU, IV for 256 possible columns.
Rows labeled by numbers 1…16384 (Office 97 allows more rows).
Cells are specified by the intersection of the column letter and row number such as F9.
Ranges which are a group of cells specified by the address of the upper left cell and lower right cell separated by a full colon.
