-// 2. const penceStringWithoutTrailingP = penceString.substring(0, penceString.length - 1): Extract the numeric portion of the penceString by taking characters from index 0 up to the last character removing the 'p'
-// 3. const paddedPenceNumberString = penceStringWithoutTrailingP . padStart(3, "0"): it ensures the penceString is at least 3 digits long by adding leading zeros if necessary

+// 2. const penceStringWithoutTrailingP = penceString.substring(0, penceString.length - 1): Extract the numeric portion of the penceString by taking characters from index 0 up to the last character removing the 'p'because 399p is not a valid number for math.

+// 3. const paddedPenceNumberString = penceStringWithoutTrailingP . padStart(3, "0"): it ensures the penceString is at least 3 digits long by adding leading zeros if necessary ensuring there will always be 2 digits for pence and 1 for pound.
