  • This calculator is not as standard as the other Texas Instruments calculators on the list. Some reviewers report that instructors and textbooks don’t often include instructions for this calculator, so students will need to teach themselves how to use it. However, there are many resources directly from Texas Instruments and many individuals available online to get you the most out of your calculator.
  • While the TI-89 calculator can compete with other calculators in the high-end graphing calculator category, it is a black and white display that might feel dated compared to other calculators in the same price range.
  • This calculator is absolutely packed with features. If you are not planning on using this calculator for advanced work, those features might be wasted. What can be challenging is that because of the many features, it takes a few more keystrokes to do more straightforward calculations, which can be time-consuming for someone not comfortable with complex calculators.

4. HP Prime Graphing Calculator

The HP Prime graphing calculator might be a lesser-known graphing calculator and not as popular as Texas Instruments calculators but it seems that some of its impressive features are sometimes overlooked. It is both easy to use but also has an incredible amount of features. While it might not be a great fit for someone casually interested in math, it’s perfect for the student who wants a calculator that they will grow into. It might have too many advanced features for a high school college course, but for college algebra, calculus, engineering, and beyond, it scales well.

FAQs on Calculators for High School and College Algebra

What is the difference between High School and College Algebra?

While this can differ from school to school, and it isn’t easy to compare all colleges and high schools to one another, one thing can be said about the differences between high school and college algebra and the pacing. High school courses generally have about 180 class days, while most college semesters have 30. College algebra classes are typically centered around instruction, leaving the practice to students independently. High school classes have a bit more time to go through content slower and generally allow for practice time in class.

When looking at high school algebra classes, the most common courses are Algebra I, Algebra II, and Pre-Cal. Based on the college, College Algebra can look more like Algebra I and II or be more for calculus readiness and look more like Pre-Cal. Regardless of the class format, calculators are generally required from day one.

What are Topics Covered in High School and College Algebra?

Again, this depends on the school and level and your course. Most high schools offer Algebra I and Algebra II as requirements for graduation. Algebra I covers all the basics of algebra, including expressions, systems of equations, functions, real numbers, inequalities, exponents, polynomials, radical and rational expressions.

Algebra II takes the topics in Algebra I and explores them on a deeper level, including linear equations, inequalities, graphs, matrices, polynomials, radical expressions, quadratic equations, functions, exponential logarithmic expressions, sequences and series, probability, and trigonometry.

Most College Algebra courses will cover topics that have been covered in Algebra I and II as well as Pre-Cal. College Algebra also includes the following units: polynomial and rational functions, Inverse functions, Exponential and logarithmic functions, Simple conics, Systems of equations, Determinants, Arithmetic and geometric sequences, and Binomial Theorem.

Where can I Purchase Calculators for High School and College Algebra?

Many of these calculators can be purchased at your preferred technology and electronics store as well as any other place you buy school supplies.
