1. Example 1: Use multiplication tricks to solve the following multiplication word problem.
   The price of a book is 48. Find the price of 500 such books.

   Solution:
   Price of one book = 48
   Price of 500 books = 500 × 48

   H T O
   5 0 0
   × 4 8
   4 0 0 0
   +2 0 0 0 x
   2 4 0 0 0_

   The price of such 500 books is 24000.

   The other way to solve this question is to simply multiply 48 by 5 and attach two zeros with the final answer. So, by multiplying 48 × 5, we get 240. But the given value is 500, so our final product will be 24000.
