Classroom PDF vs SimplexLP

Classroom PDF is designed with unique features to fit your teaching workflow. Use it to grade worksheets and walk-through answers in class. DESIGNED FOR TEACHERS There are lots of PDF apps out there, but Classroom PDF was designed specifically for classroom use. It has special features to make walking through worksheets and in-class quizzes easier. OPEN PDF FILES AND EXPORTED SLIDE DECKS Open any PDF file from other Apps (“open in…" from Dropbox etc.). You can even export PDFs directly from Keynote. ADD COVERS AND TOGGLE WITH A TAP Add covers over answers to questions, and tap to toggle them. Great for in-class quizzes or to enhance class participation. PROJECT WIRELESSLY VIA AIRPLAY Use an AppleTV or physical connector to mirror the iPad's screen to a projector. Walk around the class, and work 1:1 with students. DRAW, POINT, AND ZOOM Annotate documents with smooth ink. Write in answers or grade worksheets. Use the virtual laser-pointer to call out parts of the page. SHARE ANNOTATED FILES Email annotated or graded files to students. You can also export PDFs to 3rd party Apps such as Dropbox. STORE AND ORGANIZE ALL YOUR FILES Keep all your PDF files neatly organized with color coded categories. WE BUILD TOOLS FOR PEOPLE WHO CHANGE THE WORLD You guys have an important job, and it matters to us that you find our Apps helpful in your work. We work really hard to make sure we create the best tools possible, but we also realize that everyone's workflow is slightly different. If you have any thoughts on other features or capabilities you would find useful in your daily work, please do let us know. Your input helps us prioritize our schedules. You can reach us via the feedback page. Thanks for doing the work that you do. We hope that you find Classroom PDF helpful in its small way. Warm regards, - The App Makers @ Qrayon.

SimplexLP solves linear optimization problems, which can be mathematically described with an objective function and a set of constraints. With the new graphical representation (possible with 2 variables only) it is a lot easier to understand the theoretical concept of linear optimization! SimplexLP is the perfect learning companion for teachers (to set up problems) and students (to learn the Simplex algorithm). It is very easy to change coefficients and see how the solution varies. For the calculation the famous Simplex algorithm is used. With SimplexLP you can: – easily set up the objective function and the constraints; – solve maximization and minimization problems; – solve problems with unlimited number of variables and constraints; – solve problems with ≤, ≥ and = (in)equalities; – get all the possible solutions ("edges") to a problem; – get accurate calculations with fractions; – get your output in fractions or decimal values; – set a fixed value in the objective function, e.g. for fixed costs; – set the tab width (via a simple swipe gesture) to format the tableaus; – get a graphical representation of optimization problems with 2 variables. With SimplexLP linear optimization really makes fun!
