Texas Instruments To Casio: The Are The Best Scientific Calculators

Technology in classrooms may be evolving, but one item that has remained a constant is the need for scientific calculators. Approved for use in most major tests, including SATs, ACTs, AP exams and more, scientific calculators continue to not only be a valuable aid in completing complex math equations but also in providing an additional teaching tool in the classroom and at home.

Scientific calculators have several features, including helping students and professionals do floating-point arithmetic, logarithmic functions, exponential functions, trigonometric functions, and fast access to several commonly used mathematical functions, like pi and e.

While technological advancements mean that computing complicated math equations is easier than ever thanks to smartphones, tablets and laptops, it’s still important that students understand the computations and can explain their formulas on their own without the help of the latest technology. Thanks to scientific calculators, students can actually learn not only the answer, but the steps to get to the answer, knowledge they must be able to display during tests and exams as well as later in their careers.

From junior high to college students, as well as professionals in the medical and surveying field, finding the right scientific calculator suited to your needs can make a huge difference in one’s success. Here are three scientific calculators that fit the bill.


1. Texas Instruments TI-36X Pro

The only scientific calculator you’ll need, the Texas Instruments TI-36X Pro can take students from junior high algebra to college-level calculus.
