The following will be the result of doing 
    document.write("2" + "3");



The following will be the result of doing 
    document.write(2 + "3");




The following will be the result of doing 
    document.write("2" + 3);




The following will be the result of doing 
    document.write(2 + 3);




The following will be the result of doing the
following JavaScript.   This is an example

  var cTemp = 20; // celsius temperature is 20

The following will be the result of doing the
following JavaScript.   This is an example

  var cTemp = 20; // celsius temperature is 20
  document.write("The temperature in Farenheit is:" +  (( cTemp / 5 * 9  ) + 32 ));






Let's see if the less than sign shows up: <

Did it show up?

Let's see if the less than sign shows up: >
