What is a calculator and what are its advantages?
The history of calculators begins in 2500 BC, when the abacus was invented, a simple instrument that is known as the first equipment to be created to help with mathematical calculations.
If you still don’t know the abacus, the video below explains better how it works:
After that, there were many improvements in the calculators until we reached what we currently have, as they became portable and easy to use equipment, in addition to being very affordable.
Teachers often have doubts as to whether or not to allow the use of calculators in classrooms, as they think students will be unaccustomed.
The truth is that technology is so present in everyone’s lives today that it is necessary to use this equipment, although always with balance, of course.
Knowing how to use scientific and financial calculators is a highly valued knowledge in the job market, so it is important to let students use these tools from
he only problem for students who use these tools is that in tests and exams, this equipment is not normally allowed, especially graphing calculators, which allow a lot of information to be stored.
Professionals who use scientific and financial calculators will probably notice an increase in their own productivity after including this equipment in their work, as they provide greater agility in the calculations.
Especially the scientific and financial ones can be a little more complicated to understand, since they have many features. Some of them have tutorials and online guides that help you learn more about the functions.
Finally, a disadvantage that is mainly related to financial calculators, is that some of them have an outdated interface, which can bother some people.
See the table below about the advantages and disadvantages of calculators:
Calculator with or without printing?
Many calculators available on the market today make it possible to print a paper with the calculations performed, and can even print in color to differentiate positive from negative values.
Usually this type of calculator is seen in shops and offices, as they make it easier to check accounts. In addition, they function as a kind of instant report, which is excellent for several areas.
Depending on the use you want to make of a calculator with printing, it may be suitable or not, so it is necessary to know what your purpose is when purchasing the equipment.
Depending on the speed of the digitizer, the calculator can be very slow to print. The printing calculators that are recommended for sporadic use print 2 lines per second, those for medium use 3 lines and those for professional use 4 or more lines.
Below we have made a table with the main differences between a common calculator and a printing
A good calculator can cost between R $ 30 and R $ 1,500, depending on the use you will make of it, that is, if you are going to use it daily to make complex calculations or if it is only sporadic use.
A calculator can have a long service life, as long as the equipment is from a reliable brand and that it is well taken care of by its owner, then the price must also be analyzed from the point of view of the durability of the material.
You can get more information about the useful life of the calculator you want to purchase through the reviews of other users who have purchased the same equipment. The Internet is a great tool for discovering this type of information.
Did you know that the first mechanical calculator was invented in 1642, by Blasise Pascal, who was only 19 years old?
He wanted to help his father, who worked as a tax collector, and that’s why he invented this machine that added and subtracted. The inventor died at 39, but left a legacy that changed mathematics forever, with several lines of research in the areas of geometry and probabilities.
Where to buy?

Purchasing criteria: Main features for evaluating calculators
There are certain features that are fundamental to a calculator, such as those listed below:
- Device integration
- USB port
Below we will detail the most important features so that you can choose the most suitable equipment for you.
One of the main reasons why a person opts for a calculator is to be able to perform different mathematical operations more quickly and easily.
Therefore, there are calculator options available on the market with 400, 500 or even 2000 different functions, to cover users from the most varied areas of knowledge. Among the functions of a calculator are the following:
- Square root
- Conversion of units
- Standard deviation
- Compound interest
- Simple interest
The functions of a calculator will vary greatly depending on the type of equipment you choose, as scientific calculators are geared towards those in the exact area, while financial calculators are suitable for businessmen and students of business, accounting and economics.
Therefore, you need to know what functions you will need to use before purchasing a calculator, because depending on the area of study or work, it will be of a different model.
In addition, there is no point in buying a calculator with 2000 functions and using few of them, so you don’t end up paying more for your equipment.
The display is another important element of a calculator, as it must be easy to operate, and even users who have never had contact with a calculator should feel comfortable using its functions.
One of the main factors of a calculator is that it has a menu in Portuguese, as it is easier to know what are the functions in your own language. As the complexity of this equipment is great, having the calculator in your own language helps a lot.
The display can have one or several lines, and those with more lines are usually more didactic, as they show the function exactly as it appears in books, which allows a student to become familiarized with the equipment more quickly.
Another feature of the display is that it can be colored or not, and it is usually graphical calculators that have this feature.
The battery determines how long you can use your calculator before the charge runs out. This means that it can end at crucial times for you, such as in the middle of an important exam, or in a meeting with a potential client.
Many calculator manufacturers have chosen to provide users with options in this regard, as many devices now have recharging with solar energy in addition to the battery.
This gives extra security for those who are afraid of running out of battery in the middle of some important situation, because when the battery runs out, solar energy takes care of allowing you to finish what you were doing with the calculator.
A calculator must be sturdy, because, as they are equipment that is always in the hands, they are at risk of falling to the ground, and therefore need extra protection.
One way to protect the calculator is through a hard cover that comes with most of them. If the user places the calculator on the cover each time he finishes using the equipment, the risk that the calculator will break with a shock will be much less.
Because they are, in most cases, made of plastic, these calculators are usually durable, and many people spend long years with the same equipment. For your calculator to also last a long time, it is important that you choose calmly, and choose a manufacturer that has a good reputation in the market.
Design is another interesting aspect of calculators, as it not only determines the elegance of the equipment, but also differentiates financial and scientific calculators.
This is because, financial calculators are usually wider and short in length, while scientific calculators are longer and less wide.
The design is also important in addition to the aesthetic aspect, as the calculator must be easy to use, using separate keys to avoid typing errors and a display that is large enough for your needs.
For many people the ideal calculator must fit in their pocket, while others don’t care so much about it and want quality equipment even if it is larger than average.
Financial calculators are usually a bit smaller, and may even fit in your pocket eventually, but the printing and scientific ones have more advantageous dimensions, and, consequently, it will be more complicated to carry them everywhere.
So research before you buy and try to see the calculator in person, to check all the aspects that are important to you.
Given the technology to which we are currently subjected, calculators could not be left out, and therefore many of them are already able to connect to other devices.
This can happen via a QR code, which you just have to pair with the device you want to pair, or via bluetooth.
Through the connection with other devices it is possible that you can transfer spreadsheets, graphs and calculations between them, which helps a lot in certain areas of professional practice.
Another feature that many newer calculators on the market currently have is the USB cable slot, which allows the battery to be charged via your computer.
This is a current trend, as regular batteries often end up in the middle of important user tasks, and charging via USB is easier, as it can be connected to other devices like a computer.
Unfortunately the calculators that have USB input are still much more expensive than the common ones, but little by little this connection will start to become popular, and soon they will be at a much more affordable price.
Finally, one of the most important items to note before purchasing a calculator is its manual, as it must have clear explanations for each of the equipment’s details.
In addition, it is always important to check that it is in Portuguese, as this will make it much easier for you to understand the explanations about each of the functions.
