What’s the order of operations here?

Exponents are calculated right to left. The number in question is 2^(2^100).

When you all are done with this, can someone help me break a $20?

As a fan of numerical excesses, I second this sentiment.

Too right. I’ve a soft spot for mega and moser, though I admit Graham’s Number is a bit more the biz. (Thanks to my nephew for drawing it to my attention.)

Sure, dip it in liquid nitrogen and then hit it with a hammer. It should break pretty easily.

No need for the clear coat, just get your carbon in crystallized form, i.e. diamonds. The usual measure for diamonds is the Carat, of course. One Carat is equal 0.2 gram, so 7600 kg is 38,000,000 Carats.

38,000,000 carats. What do we have to do, blow up Jupiter?
