body: <p>I can't solve exercise three and four. I would be very pleased to get some help. Thank you in advance!</p>
  
  <pre><code>function exerciseThree(str){
    // In this exercise, you will be given a variable, it will be called: str
    // On the next line create a variable called 'length' and using the length property assign the new variable to the length of str
  
  
    // Please write your answer in the line above.
    return length; 
  }
  
  function exerciseFour(num1){
    // In this exercise, you will be given a variable, it will be called: num1
    // On the next line create a variable called 'rounded'. Call the Math global object's round method, passing it num1, and assign it to the rounded variable.
    var num1 = rounded;
    math.round (num1); 
  
    // Please write your answer in the line above.
    return rounded;
  }
