Texas Instruments TI-84 Plus Graphics Calculator

The TI-84 Plus graphing calculator offers three times the memory, more than twice the speed and a higher contrast screen than the TI-83 Plus model. It can be used on the PSAT, SAT, and ACT college entrance exams and AP tests.

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.

The TI-84 Plus graphing calculator is ideal for high school math and science. Its MathPrint™ feature engages students by enabling them to enter fractions and equations in proper notation so they see it on the display exactly as it’s printed in text and on the board.

Features include:

Take it to The Test(s)
Standardized testing organizations have approved the TI-84 Plus for use on the PSAT®, SAT®, and ACT® college entrance exams, IB® Diploma Programme and AP® tests.

Carry it from High School to College
Texas Instrument (TI) graphing calculators are durable, multi-functional educational tools that meet students’ critical math and science requirements from high school through college.
