What is a scientific calculator and how does it work?

A scientific calculator has many uses, from basic algebra to advanced trigonometrical calculus.

This mathematical device is designed to perform a wide variety of calculations. Scientific models are somewhat more complex than conventional ones since they allow you to calculate trigonometric functions, statistics, and much more. Certain calculators can even display graphs, and all have made mathematical operations much more accessible.

The origin of the calculator can be traced back to the ancient abacus. The methods of calculation have naturally evolved over time while integrating different new technologies. The first pocket calculators appeared on our desks in the 1970s. These more rudimentary versions have gradually developed into the ones we know today.

 Advantages and Disadvantages of Scientific Calculators

Advantages

  • Variety of models
  • Portable
  • Programmable
  • Perform calculations in no time
  • Relatively affordable
  • Essential for students, engineers, statisticians, etc.

Disadvantages

  • Calculate very easily but not on their own
  • Not all models integrate the same functions
  • Certain educational environments forbid their use

Shopping Criteria for Scientific Calculators

Now that you have learned about the primary aspects of scientific calculators, it is time to find out how to make the right choice. This is why we will delve into a series of key shopping criteria in the following section. Keep them in mind when you are browsing the market for your future scientific calculator, and they will pave the way for an informed and successful decision.

  • Brands
  • Intended use
  • Screen
  • Number of functions
  • Infix system
  • Power
  • Design

Brands

There are various manufacturers that design scientific calculators, the most renowned being Casio, Texas Instruments, HP, Sharp, and Canon. In comparison with other unknown brands, these renowned brands offer a degree of trust and reliability. It is essential to choose a reliable brand that will provide the degree of accuracy and durability that you expect from these devices. Scientific calculators tend to be affordable anyway, so be sure to opt for a quality product.

Intended Use

The way in which you use the scientific calculator will greatly influence the features you should look for. Some devices are designed for educational purposes, others for more advanced studies, and others still are intended for professionals like statisticians and engineers. Make sure that you choose a model whose level of calculation complexity matches your personal needs. In this article, we’ve already shown what are, in our opinion, the best choices for each brand, so that you don’t have to test every single one.

Did you know that the first truly pocked-sized electric calculator to use an LED display was invented in 1971.

Screen

Graphing calculators allow the user to easily visualize data and graphs in full color.

It may seem self-evident, but the screen of a scientific calculator is one of its most fundamental parts. You can find models on the market with single-line, two-line, single-color, or multicolor displays. While most are LCD, there are some LEDs out there. These tend to be integrated into more expensive devices that can display graphs.

Number of Functions

The number of functionalities a scientific calculator has will basically determine its range of use. The more functions, the more possibilities you have to perform all kinds of operations, both simple and complex. Keep in mind that this factor will generally be reflected in the price. You can even purchase a programmable calculator to perform operations to your liking.

Infix System

We have already discussed the different infix systems available on the market, and this certainly isn’t a criterion you should neglect if you want to pick a model that suits your needs. You will have to choose between Visually Perfect Algebraic Method (VPAM), Super Visually Perfect Algebraic Method (SVPAM), and Natural VPAM, depending on your personal use.

Power

As you know, scientific calculators can be powered by traditional batteries, solar energy, or lithium batteries. You can also find dual-use calculators with solar-powered rechargeable batteries. Conventional batteries are often seen as the riskiest decision, as you can end up with a dead battery at the worst possible time.

Design

Since it doesn’t directly influence the overall functionality of the device, the design is considered to be a less relevant factor. However, having a comfortable keyboard, a screen that you can read easily, and a device that is as light as possible can all contribute to a successful purchase. In our opinion, ergonomics and aesthetics should never be left aside

FAQs

What are the primary uses of these devices?

Scientific calculators have a massive advantage over traditional models. The range of calculations you can perform with them is much higher and there are therefore exponentially more things you can do. Some of their most common functions include square roots, derivatives, integrals, trigonometric functions, long equations, and statistics.

How are scientific calculators powered?

These devices can actually use various supplies of power. On the one hand are battery-powered calculators; simply change out the batteries when they die. It is worth noting that some models work with solar energy, a much more eco-friendly option that will give you all the autonomy you need. Other scientific calculators on the market operate with rechargeable batteries, or two different types of power supply, better known as dual batteries. They come with a lithium battery that can be charged using solar energy. This is also a much more efficient and convenient method than changing the battery every now and then.

What infix systems do scientific calculators use?

Often inscribed on the housing of calculators, Visually Perfect Algebraic Method (VPAM) is one of the most frequently used infix systems. It has revolutionized the way in which calculators write. In fact, this writing method is similar to that of mathematical programs and is also more standardized than before. The SVPAM (Super Visually Perfect Algebraic Method) is another standard infix system. The main difference with the VPAM is that you can see the expressions and the results simultaneously by displaying two lines at the same time. Besides, it allows you to make changes on the fly and recalculate. Last but not least, we have the Natural VPAM variant. This infix system is generally used in scientific calculators for students. Why, you ask? Because, in addition to including the distinctive two-line display, the different symbols are reflected on the screen to facilitate understanding.
