Boost Your Marketplace Success With Our Calculators’ Extensions!

Before setting up a company, nobody ever tells us how much math goes into running a business. If you’re one of those kids that moaned, “I’ll never use this,” during a math class, you’re now a grownup looking for online calculators. We’ve been in the same boat as you, so we’ve decided to add a free scientific calculator to our website.

## What Is a Scientific Calculator?

A scientific calculator sounds like a complicated apparatus that people in white coats use when they flap around the lab. But it’s not that scary — it’s a normal calculator that can do more complex math operations.

### Difference between a regular and a scientific calculator:

Another difference is that the scientific calculator obeys the rules of operations. For example, if you want to find out to calculate 2+2*3, a regular calculator will say it’s 12. A scientific calculator will return the correct answer, which is 8.

In the dark olden times (i.e., before the internet), you’d have to buy one of these bad boys and carry them around with you at all times — or just times you need it. Today, you can find hundreds of scientific calculators online that are similar to this one.

Why do you, as a company owner, need a scientific calculator? Let’s say you’re not in the business of solving engineering or mathematics problems.

If you’re not willing to do the math manually, a calculator can help you with the following:

### What’s the Difference Between a Scientific Calculator and a Graphing Calculator?

As the name suggests, a graphing calculator is a type of a scientific calc that comes with a high-resolution screen that can graph functions and plot coordinates. In other words, you’ll have a graphical representation of a function using the X and Y axes.

In most cases, a graphing calculator is not necessary for business-related operations.

You can also obtain a financial calculator that focuses on functions such as interest rates, cash flow, cost-sell margins, and so on.

## How to Use a Scientific Calculator

If you’ve ever held a calculator in your hand (or used an app with the same name), you’ll know your way around. The process is straightforward as you need to input numbers and select which operations you want to do with your input. Most commonly, you first enter the number and then choose a function.

All you need to know is what each button represents. Most of them are self-explanatory (like a plus sign), but we’ll go over some that may be confusing:

• MC: Clears the calculator’s memory
• M+: Adds the number on the display to the memory
• M-: Subtracts the number on the display to the memory
• MR: Recalls the memorized number
• AC: Stands for “all clear” and resets all functions
• 2nd: Assigns other functions to buttons. Think of it as a shift on your keyboard
• x!: Calculates the factorial of the number you’ve inserted
• Rand: Returns a random decimal number between 0 and 1
• EE: Stands for “enter exponent.” It adds the “x10^” phrase to your display.
• Ln: Calculates the natural logarithm function

### What Is the Easiest Scientific Calculator to Use?

Let’s face it, all calculators are simple to use once you get the hang of it. Of course, ease of use depends on the layout of the calculator. Most calculators use standard button labels, so you shouldn’t have any trouble with them, regardless of which one you use.

### How to Do Scientific Notation on Calculator

A scientific notation is a way of writing numbers that are too big or too small to be written down conveniently. For instance, let’s say the Christmas period has treated you nicely, and you’ve raked in a duodecillion dollars. That number contains 39 zeros, and instead of writing them all out, you’d use a scientific notation of 10^39.

To do scientific notation on the calculator, you need to press the EE button. Note that you need some input already on the display.

### How to Do Fractions on a Scientific Calculator

Fractions are represented by the “x/y” button. Therefore, you first need to input the numerator, press the fraction button, and then add the denominator.

### How to Calculate Sin

A sin is a function that’s equal to the ratio of the side opposite the angle you’re calculating for. So, calculating a sin is easy; we don’t know why’d you even ask this.

Joking aside, you don’t need to know any formulas with our calculator at hand. All you need to do is press the sin button and add the degree of the angle you’re interested in. The sinh button calculates the hyperbolic sine function.

## What Is the Best Online Scientific Calculator?

Online calculators can get specific and offer only a certain set of functions. Which one you pick depends on your needs, i.e., if it contains all the functions you want to carry out.

Our free online scientific calculator covers all the functions necessary for a business and comes with a simple design that won’t get you confused.

### What Is the Most Used Calculator?

Most used calculators are, obviously, physical ones. Models’ popularity depends on the buyers’ demographics and availability. Still, the most popular calculators have proven to be:

• Casio FX-115ES
• Texas Instruments TI-84 Plus
• Texas Instruments TI-30X IIS
• HP 50g
• Casio FX-9750GII
• HP-12C
• Sharp EL-W531
• Canon F-792SGA

## Summary

A scientific calculator is a helpful tool for all business owners, regardless of the industry you’re in. It can help you calculate your taxes and interest rates, better manage your time, and solve accounting problems.

Our free scientific calculator comes with all the important features that a company needs to use regularly. Use it to quickly solve any mathematical conundrums and leave that pen and paper back in the drawer.
