The 10 Best Graphing and Scientific Calculators for Algebra Grad Students in 2021-2022

Dealing with different branches of mathematics, such as trigonometry, geometry, and algebra can be very challenging and tricky. Particularly, algebra involves different theories and equations. This involves manipulating different expressions and formulas to find unknown variables. Aside from real numbers, you may also be working with a lot of matrices and complex numbers. Moreover, by drawing a relationship between constants and variables, you will also create models and graphs. 

Grad students taking up algebra will deal with higher forms of the subject and would need a more in-depth knowledge of the basics. With the help of a graphing calculator, you may be able to solve mathematical problems more smoothly and grasp concepts with the help of its features. 

Features to Lookout for 

Your calculator will be your best friend for the entire duration of your grad school life. Seeing the importance of these devices, it’s important to know what to check when getting one:

  • Battery Life – Some graphing calculators come with a built-In rechargeable battery, while others use conventional AA or AAA batteries. It’s best to take note of the rechargeable ones’ capacity and charging time. This is crucial since you don’t want to be running out of battery in the middle of an exam or report. 
  • Durability – Some calculators look sleek but are easily damaged after a drop or two, especially since graphing calculators have larger screens. Buying one is a long-term investment, so go for a durable one and may withstand constant use. Choose calculators that come with protective covers for added protection.
  • Screen Size – Graphing can take up space, and using calculators with small display areas may be inconvenient. Read up on the specifications of your selection and make sure to choose the ones with a higher line count. Touch screen ones are also a bonus but aren’t necessary.
  • Ergonomic Keys – The keys or buttons in your calculator will get much of the physical action. Choose the product that is easy to press and of just the right size. Small keys may become uncomfortable to use and may be prone to more error. Find the one with a more strategic arrangement and enough spacing in between keys.
  • Connectivity – Handling mathematical reports may need you to present data and graphs. You can easily extract computations and include graphs in your report by getting a calculator connected to a computer through a USB port. Some models come with software that’s downloadable on your personal computer, which allows you to do more with your calculator.
