+### Number of Operations: 4
+
+1. modify-overwrite-beta
+2. shift
+3. modify-overwrite-beta
+4. remove
+
+### Explanation:
+
+1. Used modify-overwrite-beta operation and concating the firstName, lastName into new key fullName also concating the keys inside address (street, city,state,zip) into address field. 
+
+created new fields:-
+
+inverse- inverse the quantity for multiplication.
+
+newPrice- using divide function to multiply the inverse of quantity to price and updating price to double.
+
+2. Used shift operation then to structure the fields to new location by shifting the newPrice in orders list.
+
+3. used modify-overwrite-beta to modify newPrice to double.
+
+4. Used remove operation removes unnecessary fields such as 'inverse' field from each item and the 'firstName' and 'lastName' fields from the customer.
