//MARKS:- OPERATORS: These are the little symbols we learnt in our arithmetics
  
  var a = 10
   a = a + 1          /* top up the value of a with 10 and it will make it 11
   a = a - 1             reduce the current value of a by 1 and it will make it 10
   a = a * a            multiply the current value of a by itself and it will  make it 100 */

   var b = 10
   b += 10                              // b is now 20
   b -= 10                             // b is now 10
 
var c = 1.1
var d = 2.2
var e = c + d                         // this will add the decimals together and gives 3.3

var name1 = "Tim McGraw"
var name2 = "Romeo"
var both = name1 + " and " + name2    // Tim McGraw and Romeo

var m = 9
var f = 2
var result = m % f                  // this returns the remainder and it is 1

                                   // comparison operators are: < , > , <= , >= , == , !=
                                  // they help to compare lefthand side operand to the righthand side

  c > d                          // is c greater than d if yes then true
  c >= e                        // is c greater than or equal to if yes then true
                               // you can negate a boolean with ! and it changes it to false if it is true
