In the war for mathematical understanding, you must choose your weapon. In this corner, the classic hardware champion, the TI-84. And in this corner, the modern, web-based challenger, Desmos.

The TI-84: The Battle-Tested Veteran. It's reliable, it's allowed on every standardized test, and its tactile buttons feel powerful.

Desmos: The Sleek, Modern Assassin. It's intuitive, it's visually stunning, and its interactive sliders are a game-changer.

The TI-84's strength is its ubiquity and test-approved status. You MUST know how to use it.

Desmos's strength is its power for exploration and discovery. It makes understanding functions a joyful, visual experience.

The TI-84's weakness is its clunky interface and steep learning curve. It feels like technology from a past era.

Desmos's weakness is that you can't use the full web version on major exams like the SAT or ACT.

The Ultimate Strategy: Train with both. Use Desmos at home to build deep, intuitive understanding. Use the TI-84 to practice for the test environment.

This isn't a choice of one over the other. A true master is proficient with every weapon.

Use Desmos to learn. Use the TI-84 to win. This is the ultimate weapon combination.
