Inspired by Hjan's answer to Don't settle for a billion, I wanted to try calculating the value of 6↑↑100 using WolframAlpha.

I've tried using 6↑↑100, 6↑100, and 6 arrow 100 to represent Knuth's up-arrow notation, but all three return financial information about Arrow (ARW) on the New York Stock Exchange.

Does WolframAlpha support Knuth's up-arrow notation? If so, how do I use it?
