For many students and professionals, having a reliable calculator that can handle their daily assignments and projects is imperative to their success. Whether you’ve gone back to school to study math and science, you need a calculator for your older child, or you’re looking for something that can help with balancing your budget at home or work, having the right calculator for your specific needs can mean the difference between solving for X and getting an F.
Not all calculators are created equal, which is why we included a variety of calculators on our list. Scientific calculators assist in geometry, statistics, biology and chemistry and can be used in situations when graphing calculators are not permitted, which is often the case in tests and exams.
Calculators with mathematic equations allow students to backtrack through calculations step by step, so they can better understand how they arrived at the (hopefully) correct answer. Graphing calculators also help students visualize their equations.
Desktop or financial calculators are more straightforward and are better adept at helping with everyday math problems involving balancing a budget, crunching numbers for a project and general invoicing. We like these calculators for home and office use.
Whatever your math needs, there’s a calculator that’s right for you. Check out our top picks below.
1. Texas Instruments TI-84 Plus CE Graphing Calculator
