In this tutorial, we will discuss the title of the JavaScript Program to multiply of Two Numbers
In this topic, we are going to learn how to write a program to multiply of two numbers in the JavaScript programming language
Multiplication of two numbers
Multiply two numbers
JavaScript program for multiplying two numbers
Program 1
Here, We use the multiplication(*) operator to find the product of the given two numbers.
The program calculates the product of the two numbers 7 and 5 , and the output is displayed here.
// JavaScript program to multiplication of two numbers
const f_Num=7;
//declare and initaiize variable for first num
const l_Num=5;
//declare and initaiize variable for second num
//calculate multiplication of given two numbers
const mul=f_Num*l_Num;
//display the multiplication of two numbers
console.log('The multiplication of '+f_Num+' and '+l_Num+' is: '+mul);
When the above code is executed, it produces the following result
The multiplication of 7 and 5 is: 35
JavaScript program for multiplying of two numbers using HTML
Program 2
Here, We use the multiplication(-) operator to find the product of two numbers. The program calculates the product of two numbers 32 and 20 then the output is displayed here using HTML
<html>
<head>
<title>multiplication of two numbers</title>
<script>
var firstNum=32;
var lastNum=20;//Decare and initiaize variabes
var mul=firstNum*lastNum;//Calculate multiplication of given numbers
document.write("Multiplication of "+firstNum+" and "+lastNum+" is: "+mul);
//print result on the screen
</script>
</head>
<body>
</body>
</html>
When the above code is executed, it produces the following result
Multiplication of 32 and 20 is: 640
JavaScript program for multiplying of two numbers using function
Program 3
The program asks the user to enter two numbers using the form , then the result of the multiplication of two numbers is displayed when the user clicks the “multiply” button.
<html>
<head>

<script>
function mul()//function to multiplication
{
var f_Num,l_Num,dif;
f_Num=Number(document.getElementById("first").value);
l_Num=Number(document.getElementById("second").value);
multiply=f_Num*l_Num;
document.getElementById("ans").innerHTML="Multiply:"+multiply;
}
</script>
</head>
<body>
<p>Enter the first Number:<input type="text" id="first"></p>
<p>Enter the second Number:<input type="text" id="second"></p>
<button >
When the above code is executed, it produces the following result
