Me in Math class: This is so pointless. When am I ever going to use this?
Me playing Magic the Gathering: If average power of creatures in the set is .85/mana and average toughness is 1.28/mana, then the set should be 57% slower than Zendikar limited, which means games should go about 12.667 turns with a standard deviation of 4.12 turns, so I should draft midrange decks when seeing fewer than X removal spells for toughness < 4 by X+2 pick.
Me playing D&D: For strength 62 at level 18, using 346 lbs as medium load for 22 strength x (4^4) for nonlinear carrying capacity scaling beyond the table, x 3 for size = 265728 lbs, when thrown weapons deal (N-400)/200 x 1d6 + 5d6 + (strength bonus) x 1.5 where N=265728, my hulking hurler deals 1331d6 = 1331 x 3.5 = 4697 per hit.
Me playing League of Legends: If my base gold generation rate is 13g/10s and Heart of Gold at 825g increases by 5g/10s, it'll pay for a Sight Ward at 75g after 2:30 and itself in 27:30 netting ((n-1650) x .5)g where n is seconds since purchasing Heart of Gold.
Me in Math class: I'm never going to use this. Why am I learning this?
