TI-84 Plus Graphing Calculator

Ideal for high school math and science. MathPrint technology engages students by enabling them to enter fractions and equations in proper notation so they see it on the display exactly as it is printed in texts and on the board. Handles calculus, engineering, trigonometric, and financial functions. Displays 8 lines, 16 characters each line. 24KB of available RAM memory. Powered by 4 AAA batteries with a lithium battery backup to protect RAM memory during main battery change. 7.8" x 6.1" x 1.3".

Expanded graphing technology performance comes preloaded with more than a dozen applications, including functionality that encourages exploration of interactive geometry, inequality graphing and real-world data collection and analysis.

Standardized testing organizations have approved the TI-84 Plus calculator for use on the PSAT*, SAT*, and ACT college entrance exams, IB* and AP* tests.

Included Apps: Cabri Jr™, Catalog Help, Conic Graphing, Inequality Graphing, LearningCheck™, Polynomial Root Finder and Simultaneous Equation Solver, Probability Simulation, Science Tools, StudyCards™ , Topics in Algebra 1, Transformation Graphing, Vernier EasyData™.
