# Mysterious Sum

Sohel vai reads newspaper every morning. The newspaper he reads contains some good features including different types of puzzle. He likes to those solve very much. In today’s newspaper the puzzle he found involves two numbers being added but with with a mysterious result. Below are a few examples:

- 4 + 2 = 62
- 9 + 6 = 153
- 17 + 12 = 295
- 5 + 5 = ?

He was quite clever and solved the puzzle quickly and happily went out for a walk. You, being his neighbor, met him on the road where he told you about the puzzle.

Given two numbers you have to find out the mysterious sum of the numbers like given above. Don’t fail to figure out the mystery behind these numbers, otherwise Sohel vai will be upset.
