Calculations can be a hectic job for many people like many are not experts in calculations and other mathematical tasks like MBA students, Mathematics students, and others like them.

What can they do then?

We have been using a solution for years, and the solution is using a calculator, but now, everything has become digitalized.

We cannot rely on some conventional tools as we need many more features, and it isn’t easy to get in a traditional calculator.

It is not wrong to say that conventional calculators are unworthy, but we can say they are less efficient, especially when we need to answer.

**What are conventional calculators?**

Conventional calculators are the typical calculators that can be used for basic calculations and complex calculations.

But keep in mind that using conventional calculators can restrict you in many ways.

If you prefer to get all the steps involved in a calculation, you cannot use a conventional or typical calculator.

These calculators are only dedicated to showing you the answers, and the steps involved in the calculation cannot be shown in these calculators.

**Typical calculators VS. Online calculators**

As mentioned above, if you want to display all the steps involved in the calculation, you must try an online tool.

But if your preference is to get the answer only, you can go for any calculator.

Both tools have pros and cons; the fundamental flaw of online calculators is that you cannot use them in your examination halls.

As getting your smartphones and other smart devices are not allowed in your examination halls, you cannot use an online calculator there.

But using a conventional calculator can be a wrong choice when you need to show up the steps, and the second thing is, you need to spend some cost on these calculators.

So, using an online calculator can be a good choice, and we have shortlisted some of the best to use calculators to calculate complex expressions.

## Best Calculators for College Students

**1. ****Integral Calculator**

Finding integrals can be a nightmare for many students, and it may not be solved without using a calculator.

If you want to get all the detailed calculations, you can go for this online calculator.

We used this integral calculator and found it very useful and helpful in solving problems related to integration and derivation.

First of all, understanding integrals are fundamental, so we can make you clear about this concept.

Integrals are inversely proportional to the derivatives, as we can say that integrals are the opposite expressions of derivatives.

It is not wrong to say that integration is essential in math and valuable in real-life problems.

**How does this work?**

All you need to enter some values, and you are all set to get your results so, the steps are discussed below.

- Specify that your function is definite or indefinite
- You need to enter a function, and you can add a symbol by clicking the keyboard symbol
- We also have an option of load example, which makes us clear that how to write a function
- After that, specify a variable to a function
- You need to enter upper bound and lower bound
- Click on the “calculate” button and get your results

**2. ****Moment calculator**

Physics is full of calculations, or we can say that complex calculations or real-life calculations are included in physics.

It is pretty clear that, without physics, we cannot solve even a single and straightforward problem related to real-life issues.

Here, we have shortlisted a calculator that can be used in physics, which is used to find a moment of force.

Many people may confuse over what is a moment? So, a moment is a product that can be retrieved by multiplying the force’s point of application and component.

This calculation can be very confusing, and that’s why we need an efficient calculator to solve this complex expression.

As this calculator is elementary, all it needs is to enter some values, and you can see these values below.

**How does this work?**

- There are three expressions, i.e., moment, force, and lever arm length so, you can select one
- Enter the value of force, and the unit of force will be in newton
- Then you need to enter lever arm length
- Enter the moment to calculate the results
- By hitting the “calculate” button, you’ll get your answer

**3. ****LCM Calculator**

LCM is one of the primary and most essential expressions of mathematics, and many things can be dependent on the LCM.

But as an essential expression, it doesn’t mean that it does not require a calculator. If you want to get an accurate answer, then you can go for an LCM calculator.

At first, presenting the basic concept of LCM, and it stands for least common multiple.

The least common multiple refers to a value that can be divided by every given number, and then it is termed LCM.

Undoubtedly, you can find out the LCM on your own, but using a calculator can be a smart choice so, you can go for them.

Sometimes, you need to see the calculation steps, and in this scenario, you need an online calculator because a conventional calculator cannot show you these steps.

**How does this work?**

- Enter two values and separate them with a comma
- Select a method from the dropdown list
- There are three methods, i.e., prime factorization, list of multiple, and division method
- Click on the “calculate” button

**4. ****Sig fig calculator**

Significant figures refer to a number with some value, or we can say that non-zero digits are essential figures.

We use a sig fig calculator to calculate significant figures as we don’t need to give many details while using this calculator.

All you need to specify is, a number and you need to set around a value that you can quickly determine by using the given scroll bar.

These calculators are straightforward to use and valuable at the same time because the significant figure is also a vital term of mathematics.

**How does this work?**

- Enter a number in the input field
- Specify a round value by using the given scroll bar
- Press on the “calculate” button
- You’ll get your answer

**Conclusion **

As mentioned above, mathematics can be a nightmare for many people, but it can be fun when we have the proper tools.

And here, we are talking about online tools because online tools are prioritized over conventional tools by various means.

The first benefit of using an online calculator is that you don’t need to spend even a single penny, so that’s something really attractive, especially for students.
