 // To begin, we can start with
 // 1. const penceString = "399p": initialises a string variable with the value "399p"
+
+
+// 2. const penceStringWithoutTrailingP = penceString.substring(0,penceString.length - 1);
+//    Initialises a string variable with the value of a new string removing the last character from penceString.
+//    "399"
+
+
+//3. const paddedPenceNumberString = penceStringWithoutTrailingP.padStart(3, "0");
+//   Initializes a new variable with the value of a new string the length of which is 3 characters.
+//   "399"
+
+
+//4. const pounds = paddedPenceNumberString.substring(0,paddedPenceNumberString.length - 2);
+//   Initializes a new variable containing a string made from paddedPenceNumberString, with the last two characters removed using the substring() method.
+//   "3"
+
+
+//5. const pence = paddedPenceNumberString.substring(paddedPenceNumberString.length - 2).padEnd(2, "0");
+//   Extracts the last two characters of paddedPenceNumberString and ensures the result is at least two characters long by adding zeros to the end if necessary.
+//   Initializes a new variable containing a string made from paddedPenceNumberString, with the first characters removed using the substring() method.
+//   padEnd() method ensures the result is at least two characters, if the string is less than 2 char padEnd adds zeros.
