My Code works really well. Can someone check out my code to see why it is so different the video solution?

var input = prompt('What is the first number'); var input1 = prompt('What is the end number');

var firstNum = parseInt(input); var endNum = parseInt(input1);

var roll = Math.floor((Math.random()*endNum) + firstNum ); var message = "<p>" + roll + " is a number between " + firstNum+ " and " + endNum + ".</p>"; document.write(message);

alert(roll);

The formula shown here is likely to generate a number well outside the requested range. For example, try asking it for a number between 1000 and 1010.

The classic formula (adapted to these variable names) would be:
ā€ƒ Math.floor((Math.random() * (endNum - firstNum + 1)) + firstNum;
