**1. Intro**

For those of you who are math lovers, you might have heard of the “square root” function. It is a very useful mathematical tool which is widely used in computer science and mathematics. It works on the concept that number 1 squared is equal to number 2 squared, and so on until it reaches unit square.

This function is extremely important for us in our daily lives because it helps us to find important numbers quickly by simply multiplying them by a certain number. For example, if we want to find 50% of a number, we would multiply it by 9 and then divide it by 100. The result will be 50% (which equals 0.5). So this calculator will help us find this answer easily.

We can use this calculator to solve equations like:

- 50% x 9 = 0.5;
- 50% x 100 = 49;
- 50% x 105 = 49;
- 50% x 1200 = 49;
- 50% x 4500 = 49; etc..

So this calculator will help us with solving problems like these. With this calculator we can also solve simple trigonometric functions like: cosine, sine, tangent etc..

In order for this online calculator to work properly, you need to enter in two numbers first before clicking on the button and then enter another two numbers after that button has been clicked on. It should be noted that as you enter in your numbers, they will get bigger because they are arranged in ascending order (from smallest number to largest one) so please do not worry about that as that won’t affect your calculation at all! Also keep in mind that when entering an equation into the calculator, you needn’t put any spaces between your letters or numbers or the function won’t be completed properly! Here are some examples of equations solved with this online calculator: cos(x) + sin(x) = y cos(y); y2 => y2 + 2x => 2y + y2 cos(x) sin(x) - sin(x) = y sin(y); y => y + 2x => 2y - y sin(x) tan(x) = x tan (y); x => tan (y) tan (0), then the result would be 3/4 => 3/4 + 3/4 => 3/4 - 3/4 ; Find all five prime factors of 404310 which equals 4142

**2. What Is a Calculator and What Is It Used For?**

In this article I will talk about single digital calculator and how it works.

A calculator is a computerized unit that can be used to perform calculations. In simple terms, a calculator is a machine that performs calculations.

For example, when you are shopping for a new car you need to compare the price of different cars and then choose the right one which is most convenient for you and makes the most sense to buy it. Basic online Calculator that can be used for simple things like addition, subtraction, multiplication and division are called as calculators. They are very helpful in everyday life like shopping, calculating bills and many more things.

**3. How to Use the Calculator Online**

Now, there are many online calculators that you can use to solve simple math problems. But, how do you choose the right one? Well, there are many things to consider and a calculator may not be the right tool for your particular needs. So, let’s look at some of the most popular online calculators to help you choose the best possible one for you.

Calculators

In this section I will discuss some of the top-rated calculators available in various platforms and give a brief overview of each one.

**4. Extra Features and Other Notes**

Calculators are supposed to be practical, right? I mean, you need to figure out your math. And this calculator is simple and easy to use. It doesn’t have too many options and it works quickly and efficiently.

Most calculators have a limited number of buttons you can use, but not this one. You can change the total, add fractions, percentages and exponents. You can also enter numbers in decimal or scientific notation. Sure, if you’re doing math homework, the entry screen might be a little intimidating for you to figure out all the numbers in one go which might not be helpful for your own calculations but there are still many features available for you to utilize if you want them.

Converting from one currency to another is made easy as well. You don’t have to know how much money is in your bank account or whether the value of a dollar bill differs from its physical appearance — the calculator does that for you! The calculator also has an option where it will display the value of items such as currency notes on their face value instead of their current price so that you don’t have to memorize prices that often!
