# TI-84 Plus CE App for Chrome OS™

Whether in a virtual or in-person classroom, this app emulates the TI-84 Plus CE on Google Chromebook™ notebook computers, allowing for exploration, visualization and better learning and understanding of math and science.

Schools or districts may purchase volume licensing from dealers.

Individual licenses are available for purchase from selected retailers.

## Key features

• Transition easily between the TI-84 Plus CE App and the
TI-84 Plus CE graphing calculator with similar button layout and menus
• Optimize your learning environment by resizing and positioning the emulator on your screen
• Start where you left off — the calculator retains its last state
• For students who need a more viewable version of the calculator, a large screen version can be accessed when turning Chromebook™ notebook computers to tablet mode (touchscreen versions only)
• Visualize concepts clearly, and make faster, stronger connections between equations, data and graphs in full color
• Distinguish between multiple graphs and plots with color-coded equations, plots and objects
• Work up to seven days offline (internet access is required for application use)
