For high school math and science students

The feature-packed HP 39g+ will help you navigate through a wide variety of middle and high school math and science classes including: General Math, Pre-Algebra, Algebra, Trigonometry, Calculus, Statistics, Geometry, Biology, Chemistry, Physics, earth sciences and more. Designed for both power and simplicity, it lets you view symbols, numbers and graphs on a dynamic split screen making side-by-side comparisons easy. Create your own applications and access the built-in electronic lessons (aplets) that help you learn new concepts at your own pace. The HP 39g+ lets you communicate easily with PCs and other HP 39g+ calculators with the included connectivity kit.

Makes learning easy
