Buying Guide: How To Choose The Best Scientific Calculator
Scientific calculators are necessary to pass highschool and universitylevel courses. That’s why almost everybody will have to buy one at some point. Let’s take a look at some of the things you should know before purchasing a scientific calculator.
Purpose
When it comes to buying any type of product, the question you have to ask is, “What will I use this item for?” Are you going to use it for examinations? For instance, if you’re using it for the SATs, then you must make sure it can be used for the said exams.
Are you going to use it for a particular class? Are you going to use it for work? Knowing this ahead of time will help you get a scientific calculator with all the functions you need. The key here is to understand your exact needs and preferences.
You may even want to consider your future needs. If you plan on taking more advanced mathematics, engineering, and science courses in the future, it may be costeffective to purchase a more advanced calculator now. This is better compared to purchasing two different calculators for different purposes.
User
This is somewhat tied to “Purpose.” Who is going to use the scientific calculator? Are you a beginner or a student? Are you an experienced engineer? The scientific calculator you will purchase will depend on its actual user.
Test Permissions
Some scientific calculators are allowed on standardized tests, while others aren’t. If you’re taking the SATs or the AP exams, you must ensure your calculator is allowed by its policies. To double check whether your scientific calculator is permitted, you can visit the official website of the examinations on the web.
Power Source Or Battery Type
Generally, there are two power sources for scientific calculators, batteries and solar energy. Solar power can give your calculator that muchneeded boost in case your batteries run out. The reverse is also true.
It’s also good to know whether the batteries are replaceable or not. You wouldn’t want to buy a calculator that doesn’t have replaceable batteries, thus obliging you to buy a new one again. That’s a serious waste of money.
Functions
Some functions to look for include probability, fraction calculations, and fraction to decimal conversions (and viceversa). These three are just tiny tips of the iceberg. A lot of calculators have hundreds of functions. A larger number of functions signifies how much the scientific calculator can do. In addition, when you have more functions, it means you have a universal calculator that’s useful for different subjects and classes.
Display
With regards to scientific calculators, display is quite broad. We’re referring to display digits, number of lines, display size, and even its clarity. Display digits refer to the scientific calculator’s number of spaces dedicated to showing numbers and symbols. Larger display digits are best for complicated equations such as those solved in trigonometry and calculus.
The number of lines refer to the number of rows the display can show. For complex calculations, the higher the number of lines, the better. Display size also matters if you want easy viewing and readability. The same goes for clarity.
Size
This isn’t much of an issue for most users. Scientific calculators are very portable at this day and age. It’s still good to know if you can carry it around your pocket. Take note that there are slim scientific calculators, and there are bulky ones as well.
Extra Features
These extras can actually help to make your life more convenient. Extra features may include the following:
 Ability to brighten or dim the display as necessary.
 Ability to store past calculations.
 Ability to turn decimals into fractions, and viceversa.
 Larger screens compared to conventional models. This allows easier viewing of graphs and calculations.
 Ability to input specific notations as they appear in a textbook (i.e., proper notation).
Package Inclusions
What are included in the package that you’re purchasing? Is there a hard case or a soft carrying pouch? Are the necessary cables included? Are there other accessories that may help you in using your scientific calculator optimally?
Price
Of course, price is always something to consider. Generally, scientific calculators are more expensive than basic calculators. A larger display, a higher number of functions, and a more robust build all lead to an increase in price. We recommend that you take all courses (present and future) into consideration, so you only have to purchase a scientific calculator once.
Warranty
This will help protect you from wasting money in case your calculator is defective. If your scientific calculator breaks down due to a manufacturing error, for instance, you can have it replaced or refunded by the company.
FrequentlyAsked Questions (FAQs)

Which brand of scientific calculator is the best?
Like most products, there is no such thing as a onesizefitsall scientific calculator. Different companies manufacture different models of scientific calculators. And all of these models vary in features and limitations. However, the most popular brands of scientific calculators include Texas Instruments, Casio, Sharp, HewlettPackard, and Radio Shack.

What is the best calculator for calculus?
We can’t say it in terms of a specific brand and model. However, you should go for graphing calculators, instead of scientific calculators. The functionalities you will need to make it the best calculator for calculus will depend on your requirements and preferences.

Is it worth buying a graphing calculator?
If you’re in a technical field, graphing calculators are necessary. They last for a very long time and are a good option for Algebra, Trigonometry, Calculus, and a whole set of subjects. If you don’t need it now, you may need it in the future. Thus, it’s better to purchase an expensive graphing calculator today compared to buying a cheaper one that you’ll soon replace in the future.

Can a graphing calculator be used as a scientific calculator?
Yes, a graphing calculator can be used in place of a scientific calculator. Technically, a graphing calculator is a scientific calculator. The difference is that a graphing calculator has a highresolution screen. It also allows you to graph functions and plot coordinates.
