 // Questions
 
 // a) When formatTimeDisplay is called how many times will pad be called?
-// =============> write your answer here
+// The pad function is called upon 3 times.
 
 // Call formatTimeDisplay with an input of 61, now answer the following:
 
 // b) What is the value assigned to num when pad is called for the first time?
-// =============> write your answer here
+// num is = 0
 
 // c) What is the return value of pad is called for the first time?
-// =============> write your answer here
+// the return value is "00"
 
 // d) What is the value assigned to num when pad is called for the last time in this program?  Explain your answer
-// =============> write your answer here
+// the value assigned is 1 this is because when the value 61 is passed into the formatTimeDisplay function it sends totalHours,
+// remainingMinutes and remainingSeconds in that order to the pad function. Since we know the remainingSeconds is sent last
+// and that 61 divided by 60 leaves us with a remainder of 1 we know 1 will be the last value assigned to num.
 
 // e) What is the return value of pad when it is called for the last time in this program?  Explain your answer
-// =============> write your answer here
+//  the return value will be "01" as when the value 1 is passed into the pad function it is converted into a string, which is "1" in this case,
+//  that string is then passed into a while loop which checks if the string is less than two characters and adds a "0" to the start of the string
+//  so "1" becomes "01" and is then returned.
