Best Calculator In India

There are many kinds of calculators available. While some can handle various operations, others are made to perform a more specific function.

Some types of calculators include graphing calculators, scientific calculators, financial calculators, and more.

With so many varieties of calculators, you are more likely to encounter either a four-function (adding, subtracting, multiplying, and dividing) or a scientific (more varied functions, such as trigonometric and logarithmic functions) calculator.

In addition, please go through the Calculator Buying Guide also, which is written after detailed research.

So How Do Calculators and Scientific Calculators Work?

Calculators are relatively simple devices. An LCD screen is used to display the numbers being entered. A few buttons are used to enter the numbers and perform the operation as requested.

The calculator uses buttons, switches, and a digital display to represent numbers. For example, when the user presses a button, and a number appears on the screen, that exact number will be stored in memory. Such calculators use a series of switches to turn on the display.

The Basic Parts of a Calculator


Among the most recognizable parts of any calculator are the display and the keyboard. We see the display when we look at a calculator – it shows us the numbers being calculated by showing us digits 0 through 9.

A calculator’s keyboard is where we enter numbers and perform the calculations.

On/Off Switch

Many calculators do have an on/off switch and a power indicator light. The button that turns the calculator on or off is sometimes called the “on/off” switch.

It is usually a small rectangular rubber button located in the top-right or bottom-right corner of the calculator.

Some devices have an indicator light showing when the device is plugged in or turned on, or even if it has a full battery charge.

Battery Compartment

Calculators also have a battery compartment where the batteries are installed. The battery compartment is located on the back of most handheld calculators.

It may take either one or two AAA batteries, depending on the type of calculator and its intended use.

If one needs to replace the batteries at any time, they can usually just pop out the old ones and replace them with new ones.

Nowadays, many calculators in India use solar power to function.

Calculator Keyboard

The keyboard is a set of keys that are located on the front of the calculator.

They have been designed to be used in conjunction with the display and created to input numbers, perform calculations, and enter some formulas as efficiently as possible.

By pressing one of these keys, one enters a new number on display or changes the number they are currently working with.

Power Supply Unit

And finally, there is a power supply unit. In most handheld calculators in India, the power supply unit is located inside of the device, usually in the area between the keyboard and the display.

It is a small circuit board with several integrated circuits and transistors that function as switches.

When you turn on your calculator by pressing the “on/off” switch, it gives power to these transistors and switches to allow power to flow into other circuits of the calculator.

Factors to look for when buying a new calculator (Buying Guide)

What should you consider when buying a new calculator? There are several factors to consider, ranging from how advanced the functions are to the calculator’s cost.

Price Of Calculator:

First, you should consider the price. The cheaper the calculator, the cheaper the materials and components used in its manufacturing.

However, a more expensive calculator is not necessarily better than a cheaper one. 

In fact, a cheap calculator might be more beneficial to your needs than a more expensive one. The key is to find a balance between the two- cost and quality.


One should consider whether they want an electronic or a mechanical calculator. Electronic calculators use electronics and computer chips to perform mathematical calculations, and they require no maintenance whatsoever. 

There are calculators for basic arithmetic operations, trigonometric functions, mathematical functions.

Also, one can find a graphing calculator, scientific calculators, a non programmable scientific calculator, a financial calculator, a calculator for statistics functions to perform fast calculations, and advanced list based statistics.

Such calculators sometimes come with dual power, have advanced functions like table function, trigonometric functions etc.

Mechanical calculators use gears and wheels to perform mathematical calculations and need occasional maintenance to keep them running smoothly.


If you are looking for a calculator, particularly for engineering students, consider purchasing one with scientific functions.

Scientific calculators contain functions specifically designed to calculate trigonometric values, logarithmic values, and mathematical formulas. 

They best scientific calculators can compute these values by determining the appropriate formula and then using it to solve the problem. 

Another feature commonly found in scientific calculators is a memory function. A memory function allows you to recall what you’ve previously entered and re-enter it, if necessary.

These are a must-buy for any engineering student in my opinion.

If you are looking for a calculator to handle standard arithmetic functions, such as addition, subtraction, and multiplication, consider purchasing a standard calculator.

In addition, consider the functions of the calculator. A calculator used in high school and college-level classes may differ from a calculator used in primary school math courses.

Engineering students will require one that can perform functions like high-level calculations while other students may want to do compound interest and permutation combination mathematic problems.

I would suggest that if you already own a handheld calculator, consider purchasing an upgrade. If you already own a calculator and are looking to upgrade or purchase a new one, make sure to check out the features that it comes with. 

For example, basic calculators may have a memory function that lets you recall what you have computed earlier.

However, an upgraded and a best scientific calculator might know which formula to use to solve a problem when it is entered.

An upgraded calculator can be a better investment than a cheaper one because it is more efficient and saves one time and energy in the long run.

Calculator Display:

(Consider whether you want an LCD or LED display.) An LCD allows you to change the contrast of the numbers on display by using the backlight button.

An LED display has no backlight, which means that one cannot adjust it. However, it can show more information than an LCD display.

Battery Type:

Solar-powered calculators use solar cells to power their batteries instead of using an electrical outlet.

This can be beneficial because it doesn’t require you to purchase batteries repeatedly and replenish them as they run out.

However, it also requires more care in keeping the calculator dry to prevent corrosion and battery leakage and keep it well-protected from harsh weather conditions.


Many calculators now come with Bluetooth technology, allowing you to connect them wirelessly to your mobile phone or tablet.

Some calculators also run by using USB cables, giving you another option to share your calculator’s results with others.


Many calculators are now made of metal, and this is one of their features. The main advantage of a plastic-bodied calculator is that it is very lightweight, allowing for much easier portability.

On the other hand, the main advantage of a metal body is its durability and its superior construction.


Some calculators come with extra-large displays that are beneficial for students interested in learning more about various functions and are also recommended for students who have vision problems.


 Consider whether or not the calculator has a tilt function that allows it to tilt up and down to simulate either an electronic display or a scientific calculator to help you learn about various functions.

Check for Any Warranty Available On The Calculator:

Calculators are relatively simple devices, and so the chances of them breaking down are pretty high.

Some calculators come with a one-year warranty, whereas others come with a two-year warranty.

Keep in mind that some retailers may offer extended warranties on these devices.

Calculator Special Keys:

Does the calculator have special keys like a GT key?
