# Top 10 useful calculators for students in 2021

When we talk about calculation or mathematics, the very first thing that comes to our mind is a calculator. A calculator is something we used to calculate mathematical figures.

We can calculate without a calculator but our calculation authentic and fully correct, we just need a calculator. And many functions can only be done by a calculator.

We found that there are numerous calculator types. Generally, we have a simple one and a scientific calculator. A scientific calculator comes along with numerous features and functions.

Some of the useful calculators are affordable or cheap but some of them are considered as the expansive ones. but the price is all dependent on the specifications a calculator has.

Here we will discuss the top 10 useful calculators for students in 2021.

## Two’s complement calculator

If you want to calculate two’s complement and you don’t have a scientific calculator then there is a choice of using an online Two’s complement calculator.

This calculator is used to calculate the one and two’s complement of a binary number. You can also find the two’s complement of any hexadecimal or decimal number.

This must be a good option when you want to do the authentic calculation and fast calculations so, you must go for this calculator.

## Perpendicular bisector calculator

This calculator is used to find the perpendicular bisector of a line due to the x-axis and y-axis. There are a group of points that are used to find out the perpendicular bisector.

We can say that this calculator is used for geometric calculation. You can do geometric calculations by using this calculator.

This online tool helps the user to calculate the perpendicular bisector for making the calculations clearer and more authentic. ## Circumcenter calculator

When we want to calculate the center of the triangle circumcircle, this tool is the best option. This is absolutely a free tool to calculate the circumcenter of a triangle.

If you want to do your calculation faster and easier then this must be the best choice. It can show up the answers in seconds and the answers are very authentic.

Without a calculator, we can’t even calculate the circumcenter due to its high calculations and decimal calculations.

## Half-angle calculator

You must study the double angle formulas. This calculator does the same but not multiplying the figure. Instead of multiplying, it divides the figure and makes it half.

The reason to use this calculator is to find out the half-angle by using an authentic source. We cannot even divide that many large amounts.

So, it is quite obvious that using a calculator is very much needed when we are going to calculate the half angles.

## Net force calculator

A net force calculator is used to calculate the net force. It is used in physics as well as in mathematics.

But we cannot find the net force of large numbers without using a calculator. So, a net force calculator is used to define the net force of the given amount.

We will get the authentic values and this is also be recommended by the professionals to use this calculator to find out the best answers.

Pro Tip: Use a time card calculator to add up your hours quickly and easily, and learn how much you’re going to get paid.

## Five number summary calculators

Five number summaries have five things that are the minimum, median, maximum, Q1, and Q3. The only job of this calculator is to find out the values by using these five values.

This calculator can be a good choice if you are willing to do your calculations on time and make them accurate.

This is absolutely a free tool that you can use online and take out the best and accurate value. By using this calculator, we can easily make our calculations easier and more correct. ## Weighted mean calculator

The weighted mean calculator is used to calculate the weighted mean and it can be done by using the different weights and combine them.

We provide different weights to the calculator and it will give the accurate value of the weighted mean. This calculator is designed for statistics.

But it can use for different subjects like mathematics and physics too. The weighted mean is nearly impossible to calculate without a calculator.

## Static friction calculator

We use this calculator to find out the friction between the surface of something and the object. This friction cannot be calculated without a calculator.

We can say that normal force is directly proportional to friction. This calculator is useful for physics but can be needed in different subjects.

This calculator can be used online without paying anything. And this could be a fast solution to your problem.

## Geometric mean calculator

This calculator contains a dial box in which you must enter the values but these values must be separated by commas.

After giving the values, there are submit values. When you are all set then this calculator gives the output.

The geometric mean is the geometric average calculation that is used in both physics and mathematics.

## DC to AC calculator

It is compulsory to have a tool that can convert DC values to AC values. We cannot do it without have a calculator or a device.

When we have to calculate the current, you must need a calculator, and this tool is considered as the best option for the conversion o direct current into the alternating current.

## Wrap up

A calculator is the basic need of every field. We are living in a digital world; we can use everything online. You can also use these tools online.
