**Notes**

- This page also solves integer and mixed linear programing problems (using the "branch and bound" algorithm). To specify which variables are required to have integer values, use the format integer x,y,z (see the examples).
- The utility is quite flexible with input. For instance, the following format will also be accepted (inequalities separated by commas): :
Maximize p = x+y subject to x+y <= 2, 3x+y >= 4 - Do not use commas in large numbers. For instance, enter 100,000 as 100000.
- Decimal mode displays all the tableaus (and results) as decimals, rounded to the number of significant digits you select (up to 13).
- Fraction mode converts all decimals to fractions and displays all the tableaus (and solutions) as fractions.
- Integer Mode eliminates decimals and fractions in all the tableaus (using the method described in the tutorial on the simple method) and displays the solution as fractions.
- Mac users: you can use the inequality symbols "option+<" and "option+>" instead of "<=" and ">=" if you like.
