3 Types of Casio Calculators in Singapore

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 Singapore, Casio is the most trusted and most popular brand. Casio calculators once ruled the world of numbers. From high school classrooms to universities and corporate companies, Casio calculators have had their 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 Calculator

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 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 Calculator

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 world of scientific calculator – the ultimate high-tech gizmo to compute all your complex calculations, algorithms, logarithms, and even graph projections. Not just any scientific calculator at that, Casio scientific calculators.

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 Calculator

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. A Casio financial calculator such as the Casio FC-100V allows 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.
