Scientific calculators became indispensable in college. That said, buying your first calculator is not always easy, especially if you haven't taken the time to learn about the subject. To give you an idea, there are 3 types of calculators: scientific, graphical, and financial calculators. Each variant has its own area of interest.

Usually, it is the functionality of the machine that takes precedence over design, screen size, and power supply. In any case, it will depend on individual preference. Let's take the example of the Casio FX-9750GII-WE Calculator which is a graphics machine dedicated to high school and university students.

### Buying Guide - How to Choose a Good Scientific Calculator?

Before going further and listing which scientific calculator to choose when you're in junior high, high school, or university, it's important to talk about the main buying criteria. In this section, we'll cover everything there is to know about features, display, and power. Here is our buying guide for the best scientific calculators.

### Functionalities

Unlike a standard calculator, scientific calculators have functionality that goes beyond addition, subtraction, multiplication, and division. Here, the term science refers to equations and curves of functions. Moreover, the performance of a machine can be judged by a variety of control buttons. The more, the better. As a reminder, there are 4 different modes which are the so-called mathematical, trigonometric, algebraic, and statistical functions.In middle school, the choice of a scientific calculator is not as complex as in high school. It's from the first class onwards that everything gets more complicated since the students who prepare a literary and scientific Baccalaureate will follow different programs.If you are preparing for a general or technological baccalaureate, the machine you need is a graphic calculator. As its name suggests, it is a machine focused on the graphical representation of mathematical functions. This variant can also handle logarithmic functions. With a graphing calculator, storing functions and their results and formulas becomes possible. A scientific graphing calculator can be recognized by the width of its screen.As for future bachelors who have opted for a scientific series, what could be better than a programmable calculating machine. Being an improved version of graphic calculators, programmable models have a large internal memory of up to 1 GB. At the same time, they will be able to store more formulas. Also, note that some models are recognized by a computer as an external device. Usually, the connection is made via a USB cable. We all know that working on a computer screen is more convenient than working on a calculator screen.

For higher education, investing in a new calculator is not a requirement unless you have decided to go to a business and finance school. In this case, the purchase of a financial calculator is strongly recommended.During official tests and exams, using a calculator that is not equipped with an exam mode is considered cheating. In a nutshell, this mode is a kind of barrier that will prevent access to the calculator's internal memory. This block can be temporary or permanent. Unblocking is done either by a computer or with the help of another calculator.

### Quality of the display

It is on the screen that all graphs and results will be displayed. A good visual rendering is one of the qualities of a good calculator. The screen resolution itself is not synonymous with quality if the screen is too small. Screen size is very important, especially for graphing calculators.Apart from the size and sharpness of the display, the color of the screen can be a source of annoyance if it is not well proportioned. The best thing to do is to consult the users' opinions if there are negative remarks on this subject. As a matter of fact, relying only on a price comparator is not the best solution. As for the number of lines, it all depends on your habits. Nevertheless, working with a single-line calculator is much more constraining than with a 2 or even 3-line model.**Battery**A scientific calculator works with either a battery or a battery. The question is whether you are going to use it daily or only occasionally. If it's for regular use, the battery is still the best option. In some models, the battery is rechargeable. In addition, batteries have much greater autonomy and lifespan than a battery. Also, make sure it is included in the purchase, otherwise, you will have to pay for one. Note that each machine has its own specificities. All this information is available on the website where you will place your order. Seen in this light, knowing where to buy a new scientific calculator not only saves a few dollars but also time. The advantage of batteries is that they are less expensive. On top of that, they're easy to find. But whether it's one or the other, having a spare battery or a spare battery will prevent serious problems. In fact, there is nothing stressful about running out of batteries in the middle of an exam.
