Although there are many free online math resource sites the one I personally have found to be incredibly helpful for students and parents alike is CoolMath.com (http://www.coolmath.com/). This site is attractively set up to engage youth and offers a variety of lessons, games, puzzles, art and even a math dictionary just to name a few things. This site can assist a student with everything from simple addition to calculus and does so in a fun and exciting way doing just what the title implies and that is making Math cool. ...

Solving Linear Programming using QM for windows or Solver in Excel

Formulate a linear programming model for the below set of problems. For those problems, solve the linear programming model by using the computer. You can use either QM for Windows or Solver (in Excel) to solve these problems.
If using QM for Windows, you can capture the results and a graph in one of two ways:
? By doing a "Print Screen," you capture the screen image. You can now copy directly to Word (or to Paint, and then to Word).
? Or you can save data from QM for Windows as an HTML file. You can only save data one window at a time. Highlight the QM for Windows output window you want to save and select Save As HTML. You can then edit the HTML file in Word to your liking, or you can copy it directly to Word.
? If you use QM for Windows, please include the results screen and the Graph in the Word document you create. Follow the format of the examples that were posted in the Doc Sharing tab. Include the model formulation or a window showing the constraints. Save the resulting file as a Word file.
If using Solver, please submit the Excel file (include the model formulation on the worksheet). If using an Excel document, put one problem per worksheet, label all worksheets and put all problems in one file.
