This is another important concept in mathematics applied over fields like probability and statistics where you are asked to calculate the number of ways you can select items from a larger set, where the order will not matter. For instance, you might have a group of persons, and you want to form a team comprising of a few of those individuals. Combinations will then help you calculate how many different teams may be formed there, regardless of which order you would choose the members in.
Combinations can be calculated using a mathematical formula, but if the numbers involved are large, it is cumbersome and prone to error. The Desmos online scientific calculator helps in such situations. It is an easy way to compute combinations with ease and without errors.
What Are Combinations?
The word combination means picking items from a group where the arrangement does not matter. Suppose that you have five friends, Alice, Bob, Charlie, David, and Eve. If you want to go see a movie and can take two friends along, then some of the combinations would be Alice and Bob, Alice and Charlie, Bob and David, etc. Notice that the order doesn’t matter – picking Alice and Bob is the same as picking Bob and Alice.
The Desmos online scientific calculator helps you calculate these combinations easily by inputting the total number of items and the number of items you want to select. It will then give you the result in no time, which can be quite time-saving when dealing with larger numbers.
Using the Desmos Scientific Calculator
Desmos provides a free online scientific calculator that is easy to use and can perform many types of mathematical operations, including combination calculations. To begin with combinations, you simply need to access the calculator through the Desmos website. Here’s how to use it:
- Open the Desmos Calculator First, go to the Desmos website and open the free online scientific calculator. It is free to use from any device that has internet, and you don’t need an account.
- Understand the Layout: The Desmos interface is clean and intuitive. You will see a variety of buttons for basic operations such as addition, subtraction, multiplication, and division, along with buttons for more advanced functions, including trigonometric and logarithmic operations.
- Combinations. You can calculate combinations using the combination function in Desmos. It is a built-in function that will help you easily find how many ways you can choose a certain number of items from a larger set. For example, if you want to know how many ways you can choose two items from a set of five, just enter the values into the Desmos calculator, and it will compute the result instantly.
- Work with Large Numbers: When you need to work with larger numbers, Desmos can also take care of that. Simply type in the total number of items and the number you are selecting, and it will compute your answer rapidly even for intricate combinations involving large values.
- Manual Factorial Calculations: Although Desmos makes combination calculations easy, you can also use it to calculate factorials. Factorials are part of the combination formula. You can find the factorial of a number by typing the number followed by an exclamation mark, and Desmos will immediately provide you with the factorial value.
Why Choose Desmos for Combinations?
There are several reasons why using the Desmos online scientific calculator for combination calculations is a smart choice:
- There are many reasons why using the Desmos online scientific calculator on combination calculations is a smart move.

- Speed: You can calculate combinations using Desmos in a few seconds. This is faster than calculating factorials and doing complex division in problems involving combinations.
- Free Access: Desmos is free to use. You will not need to buy any software or download something to start using the calculator. This makes it an excellent tool for students and professionals alike.
- User-Friendly Interface: If you are not well conversant with scientific calculators, the interface of Desmos is easy to use. The combination function, among other functions, is found easily, so everyone can easily access it.
- Versatility: Besides combinations, Desmos has many other functions, including graphing, trigonometry, and algebraic operations. This makes it a one-stop solution for a variety of mathematical tasks.
Example: How Desmos Helps with Combinations
Let’s try a simple example to see how Desmos may help you solve combinations:
For example, say you want to know how many ways you may choose three from a group of eight. It is as easy as typing into the calculator: the result pops up immediately without any need for calculating factorials or doing long division.
This is very useful when working with larger sets because manually calculating combinations can be quite time-consuming and prone to errors. Desmos will do all the math for you, freeing you up to think about the meaning of the results and how they might apply to real-world problems.
