Thank you for your review
xNumberLines is a program for generating number lines with solution sets to algebraic problems (such as inequalities). These diagrams are frequently used in middle school and high school math courses. This program will automatically generate the graphical solution diagrams when you input algebraic expressions such as "x < 3" or "-2 <= x < 4". The diagrams can then be exported, copied, or dragged into other applications such as Microsoft Word, Powerpoint, Keynote, Create, OmniGraffle, etc.
