Operations supported:
1. Addition

5. Square root
Displays the result both in Arabic & Devanagari numerals. Result in Arabic numerals is shown in the first beside the input & the second row shows the result in Devanagari numerals. (For reference on Devanagari numerals please see - https://en.wikipedia.org/wiki/Indian_numerals).
Error cases like division by zero, and trying to take square root of a negative number are properly handled.
