### Advantages & Disadvantages of Calculator Usage

Calculators are one of the most powerful tools in the education market. They help teach children how to solve math problems with ease. They also provide several advantages for mathematics teachers, such as making it easier to develop curriculum and grades.

However, some disadvantages come along with calculator usage in school, like the lack of skill development of students due to their reliance on calculators.

### Use Cases for Calculators in the Classroom

The use of calculators in the classroom is a contentious issue. Some people think that calculators should not be used at all because they are not good for math skills development. But, there are many benefits to using calculators instead of pen and paper. Besides, they are more accurate than pen and paper due to the built-in features that reduce errors.

Some studies have shown that calculator usage can slow down the acquisition of math skills because students tend to rely on this tool more than solve problems by hand. Therefore, students who use calculators may end up with worse math skills than those who do not use them at all.

On the other hand, some teachers believe that introducing calculators in the classroom is a good idea as it will allow students to find ways to solve math problems faster.

### Why Teach Kids to Calculate with a Calculator?

Calculators are needed in today’s world for many reasons. They help us to solve mathematical problems quickly and correctly. They also reduce mental fatigue, which can be helpful when doing math problems for long periods.

There are many benefits to using calculators in the classroom. The most important one is that they make it easier for students to learn mathematical concepts because they can actually see how calculations will turn out instead of guessing what the answer will be. This allows students to correct their mistakes quickly and without much frustration over not knowing how to do it right.

It is also helpful for kids who don't know how to calculate without a calculator yet because they can use it to figure out what they need to do before solving the problem with a pencil and paper or on a whiteboard.

### The History of Calculators

Before the discovery of a mechanical calculator, people used to use a calculation device called the Abacus.

The abacus is a tool that has been in use since 500 BC. It is based on decimal system with beads on wires which are used for calculations. The modern version of the abacus is made up of rows and columns with each column equivalent to one decimal digit.

The history of calculators can be traced back to the 16th century with the invention of "Napier's Bones". John Napier created this device with 10 bones which could serve as a multiplication table and could be used to calculate division, addition, and subtraction quickly.

But it wasn't until 1642 when Blaise Pascal invented "Pascaline" a mechanical calculator that was powered by gears and was the first successful calculator.

### How can a Calculator Help Me in the Classroom and Outside

Calculators have been an essential tool for students to use in the classroom and outside. Teachers assign calculators as a class project to teach the basics of math skills. They are also excellent tools for solving complicated mathematical problems that are difficult to calculate by hand.

Calculators can help everyone, not only children but adults as well. Calculators can be used at home or at work to save time and make calculations faster. They are especially beneficial if you need calculations for money-related tasks like balancing a checkbook or calculating interest rates on savings accounts.

Calculators do many things like adding, subtracting, multiplying, and dividing numbers quickly and accurately, converting units of measurement like Fahrenheit or Celsius into each other, finding factors of numbers, solving equations with fractions, and more!
