 // Questions
 
 // a) When formatTimeDisplay is called how many times will pad be called?
-// =============> write your answer here
+// =============> write your answer here: three calls to pad() in the return statement:
+//return `${pad(totalHours)}:${pad(remainingMinutes)}:${pad(remainingSeconds)}`;
 
 // 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
+// =============> write your answer here:
+//For formatTimeDisplay(61):
+//remainingSeconds = 61 % 60 = 1
+//totalMinutes = (61 - 1) / 60 → 1
+//remainingMinutes = 1 % 60 → 1
+//totalHours = (1 - 1) / 60 → 0
+//num = 1
 
 // c) What is the return value of pad when it is called for the first time?
-// =============> write your answer here
+// =============> write your answer here:num is 0.
+//let numString = num.toString(); gives us 0
+
+// This loop adds a "0" because the string has only one character:
+//numString = "0" + "0";
+//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
+// =============> write your answer here:
+//The last call is:   pad(remainingSeconds)
+
+//For 61 seconds, remainingSeconds is 61 % 60 = 1:
+//so num = 1
 
 // 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
+// =============> write your answer here:
+//num is 1, so:
+//num.toString() gives "1".
+
+// and this loop adds a 0 to the beginning: "01"
+
+//So the final result of formatTimeDisplay(61) is: 00:01:01
