//Q5) Write a program that take two numbers and add them in a new variable.Show the result in your browser.
// var num1=3;
// var num2=5;
// var result=num1+num2;
// console.log("Sum of "+ num1+" and "+ num2+" is "+result)

//Q2) Repeat task1 for subtraction, multiplication, division and modulus.
// var num1=3;
// var num2=5;

// //Subtraction
// console.log("Subtraction of "+num1+" and "+num2+" is "+(num1-num2));

// //Multiplication
// console.log("Multiplication of "+num1+" and "+num2+" is "+(num1*num2));

// //Division
// console.log("Division of "+num1+" and "+num2+" is "+(num1/num2));

// //Multiplication
// console.log("Modulus of "+num1+" and "+num2+" is "+(num1%num2));

//Q3) Do the following using JS Mathematic Expressions
//a) Declare a variable
//b) Show the value of variable in your browser like "Value after variable declaration is:??".
//c) Initialize the variable with some number.
//d) Show the value of variable in your browser like "Initial value: 5".
//e) Increament the variable.
//f) Show the value of variable in your browser like "Value after increament is: ??"
//g) Add 7 to the variable.
//h) Show the value of variable in your browser like "value after addition is: 13".
//i) Decrement the variable.
//j) Show the value of variable in your browser like "Value after decrement is: 12"'
//k) Show the remainder after dividing the variable value by 3.
//l) Output: "The remainder is : 0".


// //a)
// var num1;
// //b)
// console.log("Value after variable declaration is undefined");
// //c)
// num1=20;
// //d)
// console.log("Initial value: "+ num1);
// //e)
// num1++;
// //f)
// console.log("Value after increment is: "+num1);
// //g)
// num1+=7;
// //h)
// console.log("Value after addition is: "+num1);
// //i)
// num1--;
// //j)
// console.log("Value after decrement is: "+num1);
// //k)
// num1%=3;  //num1=num1%3
// //l)
// console.log("The remainder is: "+num1);
