Word Problems on Addition of 3-Digit Numbers

Examples:

1. Tom has 512 pencils in his box. His friend gives him 161 more pencils. How many pencils does Tom have now?
   • 512 + 161 = 673
   • Answer: Tom has 673 pencils now.
2. A bookshelf has 517 books on it. If 232 more books are added, how many books are on the bookshelf now?
   • 517 + 232 = 749

   • Answer: There are 749 books on the bookshelf now.
