How to Calculate Factorial

## Online Scientific Calculator With Factorials

Enter any main number and it will display a series of outputs, including the factorial. The number of outputs is proportional to the number of significant digits in the number.

### Calculator

This free online science calculator can be used as a common scientific calculator with functions such as: sin, cos, log, power, root, and memory. However, our calculator also includes a molecular weight calculator and the tables with various physical and chemical constants. This scientific calculator contains a list with task history, storing all the recent inputs and results. Scientific calculator displays the numbers rounded to a user-specified number of decimal places.I greatly appreciate the accuracy and flexibility of this calculator. It's very nice that I can use variables and nest functions, and the functions never seem to completely "zero out" due to a failure of precision like most calculators that are available for calculating hyperbolic trig functions. Especially since I am working with special relativity, where almost every single "daily life"-scale velocity is unbelievably small compared to the speed of light, so I am usually working with fractions on the order of a few billionths or smaller.

Scientific calculators simplify the process of inputting and calculating more complicated expressions than standard calculators. Ordinary calculators can handle factorials, but you have to enter them manually, and this can be time-consuming if you’re taking the factorial of a bigger number. Scientific calculators make this much easier, with most of them including a “x!” key purpose-built for evaluating factorials. All you have to do is enter the number you want to take the factorial of and then press this key to evaluate itFinding the “x!” key on your calculator will be the most challenging part of the operation. In some cases, the key is found on a secondary or tertiary function, with the symbol above the button you need to press rather than on it. In these cases, you need to press the “shift,” “2nd” or “alpha” key to activate the corresponding function for the key. These buttons are often color-coded to make it clear which button you need to press. With this type of calculator, press the button you want to take the factorial of, press the button for the necessary function, then press the factorial button and finally hit “=” for the answer.

### Math

At first I thought this app was an amazing calculator and loved that it was customizable, I got a free trial and was unable to cancel when my phone stopped working for a week when I dropped it in water so I got charged. I wasn’t too upset that I accidentally bought it for a year until now. I used to use the graphing features for my math class but now that I’m using it for exponents it often gives me the wrong calculations. For my Chemistry class we need a calculator during class and for tests and my final calculations have been wrong. I’ve shown my teacher what I’m inputting and all my steps are correct and it’s the app that occasionally will give the wrong calculations. This doesn’t happen all the times, but it’s very upsetting to know I paid for a calculator that isn’t guaranteed to give me the proper accurate calculations all the time. I truly believed the calculator app was going to be a great substitute I would recommend, but it’s unreliable and for that reason I would not 100% suggest it to others.

Extra buttons on a scientific calculator do more than basic operations. We’ll show what each button or function looks on a scientific calculator. Then, we’ll explain how they are used to solve math problems.On graphing calculators, you may need to do even more to do a factorial. For example, on the TI-84 Plus, you need to enter the math probability menu by pressing “[math]” followed by the left key twice, and finally press “4” to enter the factorial symbol. Check your manual to find the way to complete the operation on a specific graphing calculator. (Source: sciencing.com)

On our Online Scientific Calculator, you will find several buttons on the interface. Aside from the obvious 0 to 9, a decimal point, the four basic operations, the equal sign (+, -, x, ÷, =), and the parentheses () for entering complex mathematical expressions. Additionally, there are 27 more buttons, each with a specific function. (Source: www.mathgoodies.com)
