Because it is such a specialized device as compared to your smartphone, its also often quicker and easier to use than a graphing calculator app.įinally, making use of graphing calculator functions on a smartphone would require downloading a third party app that could potentially be unreliable, costly, hard to use or even contain malware. The TI 84 device is often allowed to be referenced in testing & school environments that otherwise prohibit smartphone use. Graphing calculators still have a purpose though. While graphing calculators existed long before smartphones were around to compute specialized Calculus and Algebraic functions, today, there almost certainly “is an app for that” to achieve similar results. Why do you need one (when you’ve already got a smartphone)? Just scanning over the list of modules to learn more about the device gives you an an appreciation for all the things this device can do. Texas Instruments, the manufacturer, has a helpful FAQ guide for parents about why a calculator is helpful and learning modules or guides to learn how to use the TI-84 Plus. You need to apply your understanding of a concept to make efficient use of them. Graphing calculators don’t just “give” you the answers. And it’s important to note that graphing calculators are not a cheat. Instead of having to convert the data (from long mathematical equations) they see on the board into other numbers, students can enter fractions and equations in proper notation and run computations and graphs. Being able to visualize the data (from Calculus, Statistics, Economics, Physics, and a number of other areas of study) is powerful. TI-84’s also come preloaded with many related apps to help students better collect, input, and analyze-real world data. In a nutshell, the TI 84 is a powerful calculator for students to create more complex graphs and solve higher math equations. ![]() What is a TI 84 Calculator?Ī TI-84 Calculator, sometimes called a TI-84 Plus or a TI-84 Plus Graphing Calculator, is the gold standard right now for math, science, and statistics courses in high school (and beyond). This article takes a look at what a TI 84 calculator is, why students actually need them, and what TI 84 calculators can do. You may be wondering why you need to buy one, especially since every high schooler already has a pocket computer (smartphone) where you can google just about anything. From high school through college, students will crank out plenty of powerful graphs with these calculators. The TI graphing calculator tops school supplies lists for high schoolers across the nation.
