 // Questions
 
 // a) When formatTimeDisplay is called how many times will pad be called?
-// =============> write your answer here
+// =============> The pad function is called three times on line 15.
 
 // 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
+// =============> The value assigned to num is 0.
 
 // c) What is the return value of pad when it is called for the first time?
-// =============> write your answer here
+// =============> The value of pad when it is called for the first time "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 assign to num is 1.
+//  because the last call to pad is pad(remainingSeconds), and remainingSeconds is 1
+// when formatTimeDisplay(61) is called.
 
 // 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 is "01" because the last call to pad is pad(1).
+// The pad function add a zero to make the number two digits.
