Math is crazy

Sometimes the math of really large numbers is difficult to understand.

Take a deck of 52 cards and give it a good shuffle. That order is almost certainly unique—no deck in history has likely ever matched it exactly. Why? There are about 80 unvigintillion (8 followed by 67 zeros) possible ways to arrange those cards, a number so huge it dwarfs the estimated 200 sextillion stars (2 followed by 23 zeros) in the observable universe by trillions upon trillions of times. Math is wild!
