+// Line 14 to 16: New variable declared called pence, equates to paddedPenceNumberString. The .substring method is used to create a new string, which is paddedPenceNumberString.length which is 3, the -2 which is 1. 
+// because only one index is called, that being 1, the second index, this means that 1 and everything after it is included. 
+// Then .padEnd method is used, which is the opposite of padStart, it pads the ending of the index in the case of string length being short of specified length. 2 is the length and 0 is the padding character, which is not needed in this case because string meets length.
