Explanation:
2 Buildings : 3 Floors Each : 16 Windows per Floor
Multiply 2 and 3 to get the total amount of floors. 
2 times 3 equals 6 
Then, multiply 6 and 16 to get the total amount of windows in the Park View Buildings. 
6 times 16 equals 96 
Therefore, there are 96 windows in total or 48 windows per building
