In this tutorial, we will discuss the title of the JavaScript Program to substract Two Numbers
In this topic, we are going to learn how to write a program to subtract two numbers in the JavaScript programming language
Program 1
Here, We use the minus(-) operator to find the differences between the given two numbers. The difference between the two numbers 24 and 14 and the output is displayed here
//Caculate subtraction of two numbers in JavaScript const f_Num=24; const l_Num=14; //declare and initaiize two variable //calculate difference of two numbers const dif=f_Num-l_Num; //display the difference of two numbers console.log('The subtraction of '+f_Num+' and '+l_Num+' is: '+dif);
When the above code is executed, it produces the following result
The subtraction of 24 and 14 is: 10
Program 2
Here, We use the minus(-) operator to find the differences between two numbers. The difference between two numbers 15 and 20 , the output is displayed here
<html> <head> <title>Subtraction of two numbers</title> <script> var f_Num=15; var l_Num=20; var sub=f_Num-l_Num; document.write("subtraction of "+f_Num+" and "+l_Num+" is: "+sub); </script> </head> <body> </body> </html>
When the above code is executed, it produces the following result
subtraction of 15 and 20 is: -5
Program 3
The program asks the user to enter two numbers using the form and, then result of the difference between two numbers is displayed when the user clicks the “subtract” button
<html> <head> <title>subtract two numbers</title> <script> function subs()//function to subtraction { var f_Num,s_Num,dif; f_Num=Number(document.getElementById("first").value); s_Num=Number(document.getElementById("second").value); dif=f_Num-s_Num; document.getElementById("ans").innerHTML="Difference:"+dif; } </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
