Huge thanks to Mr. Ravi Tomar & Mr. Praveen of @CISFHQrs at Delhi Airport for swiftly locating my wife’s misplaced passport. Their professionalism & dedication turned a stressful moment into relief. Outstanding service by the CISF team! #CISF #AirportSecurity

Well done for the nerd sniping! I wrote a little #JuliaLang code and let my computer crunch the 4s for me.

For 33, we either need the Decimal Point or something such as the Square(X) operation. Here's a possible solution with Square(X) for 33: Square(4) + Square(4) + (4/4)

Here’s a possible solution for 51: {Square(4!) + Square[Square(4)] - Square(4)} / Square(4) You can arrive at the above using a very straightforward approach such as: 51=36+15=Square(3x2)+Square(4)-1 Now, 3x2=4!/4, and hence the above solution.
