Calculators have always been gadgets that were necessary. Since we were in high school, we had to use calculators to compute our numbers. Casio calculators were most often the preferred choice. Here are 3 types of Casio calculators you would have encountered in your lifetime.

3 Types of Casio Calculators in Hong Kong

We live in an age where computers do all the work for us. Simply punch in some numbers and words into a computer, smartphone, or tablet, and you’ve got all the algorithms, complex calculations, and insane computing done within a split-second. But we cannot run away from the basics – the basics of calculations – Calculators. Among the most prominent of the calculator brands in Hong Kong, Casio is the most trusted. Casio calculators once ruled the world of numbers. From high school classrooms to universities and corporate companies, Casio has had its place in every step of our life. Here are 3 types of Casio calculators you may have come across (or are using till this day).

Casio Basic Calculators

1 + 1 = 2 In order to create a machine that can compute that input within a millisecond, you will need years of research. Casio did exactly that when the Japanese company took a step into the world of electronics. Casio basic calculators were the go-to gadget of the 80s, 90s, and early 2000s when any calculations were necessary. From grocery stores to financial advisors, everyone had a Casio calculator in their pencil case along with the other necessary stationery. But what made these devices so handy is their ability to compute multiple functions. Here are some calculations basic calculators are able to do:

  • Addition
  • Subtraction
  • Division
  • Multiplication
  • Percentage
  • Square root

Casio Scientific Calculators

Back in the 80s and early 90s, we would have imagined basic calculators to be the most advanced gadget for calculations. But one calculator makes the basic calculator seem like the Stone Age.

Enter the scientific calculator – the ultimate high-tech gizmo to compute all your complex calculations, algorithms, logarithms, and even graph projections.

If you’ve ever studied higher-level mathematics such as Calculus or Algebra, the first thing you will need when attending a class (besides the textbook) is a scientific calculator. 90% of the time, the lecturer will advise you to use a Casio scientific calculator. “It is more reliable” was the reasoning behind it – and it’s true! Casio scientific calculators are precise, accurate, and are able to anticipate your next action along with prompts to guide you on what your next options are. One of the big plus points of Casio scientific calculators is the ability to use functions. Functions such as logarithms (sin, cos, tan) along with long, complex calculations can be pressed into the scientific calculator, and the answer will be out in no time.

Casio Financial Calculators

Now we graduate into the working world, into the world of finance. Planning our finances is a vital part of our life. Whether we plan finances for a living or simply calculate our investments towards our retirement fund, we all need financial calculations done. Thankfully, Casio financial calculators make light work of our task. Casio financial calculators such as the Casio FC-100V allow you to accurately calculate financial projections such a Time-Value of Money, Return of Investment, and Interest Rate Percentages with precision and accuracy.

These three types of Casio calculators may seem obsolete in the race for faster, more efficient technology and computing. But don’t be fooled, Casio calculators have always been a stepping stone to the modern world. Millions of calculations done on these devices have enabled geniuses to invent, build, facilitate, and plan the infrastructure and the world we live in today.

How do I know if my Casio calculator is original?

Here are a few ways to check whether your Casio calculator is original:

  • The build quality: A Casio calculator should be of high quality. The hard case should slide on easily, and the edges around the calculator should be smooth. On the fake unit, the hard case will be difficult to slide on, and there’ll be imperfection on the plastic body which feels of low-grade material.
  • The keys: On the real deal, all the keys are smooth, silent and low-travel keys. On the fake copy, the keys have a low-quality feel and make noise whenever you hit them and sometimes, they get stuck.
  • The display: On the real Casio calculator, the display should be clear and readable. On the fake one, the display will be somewhat fuzzy.
  • The “Power On” display: On a genuine copy, when you press the “ON” button, it turns on, showing the ‘zero’ digit, and while still on, if you press the “ON” button again, the display momentarily goes and back on again. On the ‘Knock-off,’ once you turn it on and press the “ON” button again, nothing happens.
  • Fine-tuning: In most calculators, some different features and options can be tweaked with the push of a few buttons in order to improve the user experience; on the fake calculator, the options for changing things such as the contrast are present but don’t work.

Is Casio FX991ex allowed in exams?

All calculators are allowed in all exams (except GCSE non-calc paper). Graphic calculators are also allowed in GCSE and A-Level, as long as they don’t do algebraic manipulation (ex: expanding and factorising).
