詳細情報
Lotus 1-2-3 was first developed by Lotus Development Corporation, which was bought by IBM in 1995. The "1-2-3" refers to the program's three main capabilities: 1) spreadsheet functions, 2) creating charts and graphs, and 3) basic database operations.
注: Lotus 1-2-3 was popular in the 1980s and early-90s. However, it was overtaken by Microsoft Excel in the 90s and was officially discontinued in 2013.
