Here is a wonderful small teaser I got from the site brilliant.org. I have seen at least two solutions to this puzzle, so try your creativity, there might be more.
Look at the equation
1 4 9 = 16
Add any mathematical operators in the above equation to balance the two sides, with the following exceptions:
- Cannot use “not equal to” sign
- Cannot use any operator that requires you to use a digit
As always, please send your answers as comments within the blog (preferred), or send an e-mail to firstname.lastname@example.org. Please do share the puzzle with others if you like, and please also send puzzles that you have come across that you think I can share in this blog.
Happy New Year!
