• Support for .tns files containing images (.jpeg, .jpg, .bmp, .png formats) that are overlaid with graphical elements or inserted on interactive notes pages
• Explore mathematical expressions in symbolic form, see patterns and understand the math behind the formulas
• Visualize multiple representations of a single problem-algebraic, graphical, geometric, numeric and written
• Chem Box feature allows easy input of chemical formulas and equations
• Manipulate linked representations of properties to instantly update the others and show meaningful connections without switching screens (for example, grab a graphed function and move it to see the effect on corresponding equations and data lists)

Programming
