Sum of two numbers using javascript

Introduction:

In programming, it's essential to understand basic operations such as addition, subtraction, multiplication, and division. One of the most common operations is finding the sum of two numbers. In JavaScript, we can easily find the sum of two numbers using the "+" operator. This simple operation forms the building block for more complex programming concepts. In this article, we will explore how to find the sum of two numbers using JavaScript.

Source Code:

Explanation:

In above program we define variable num1 for first number with value 12 and num2 for second number with value 26. Addition of num1 and num 2 stored in variable sum and it display on the page with docuemnt.write() statement.

Ouptut:

Sum=38

We can also write the program by prompting from the user to calculate the sum of two numbers using javascript.

Explanation:

In above program we assign the variable a for first number , b for second number and s for sum of two numbers. We use prompt( ) function to prompt the user to input two number and stored in the variable a and b.

To calculate the sum (s=a+b) we used here arithmetic operator ( + ), where value of a and b is going to add and result is going to be stored in the variable s.

At last, the program we use document.write() function to display sum for the user on the page.

FAQ:

Q: What is JavaScript? 

A: JavaScript is a programming language used to create interactive web pages and web applications.

Q: How do I add two numbers in JavaScript? 

A: To add two numbers in JavaScript, you can use the "+" operator. For example, if you want to add 2 and 3, you can write: 2 + 3.

Q: What happens if I try to add a number and a string in JavaScript? 

A: If you try to add a number and a string in JavaScript, the result will be a string. For example, if you add 2 and "3", the result will be "23".

Q: Can I add more than two numbers using the "+" operator in JavaScript? 

A: Yes, you can add more than two numbers using the "+" operator. For example, if you want to add 2, 3, and 4, you can write: 2 + 3 + 4.

Conclusion:

In conclusion, JavaScript provides an easy and efficient way to calculate the sum of two numbers using javascript. The addition operator (+) allows us to perform arithmetic operations on numerical values and obtain the result in no time. Additionally, we can also use JavaScript functions to make our code more organized and reusable. By applying these techniques, we can create robust and reliable applications that can handle various mathematical calculations. Whether you are a beginner or an experienced developer, mastering the basics of JavaScript can greatly enhance your programming skills and enable you to build complex and sophisticated web applications.
