At my favorite drugstore, comic books used to cost 10¢ .
(It wasn't yesterday, or even last week. In fact, the drugstore
was burned to the ground during the riots in 1964, and never
rebuilt. But I digress.)
Normally, my parents only let me buy one comic book at a time.
But before I left for summer camp, I could empty my little piggy
and spend it ALL on comic books, all at the same time ! That
was as much fun as the whole 2 weeks at camp !
I emptied my little pig. I had 67¢ in there. I headed for the
drugstore. For the whole rest of the afternoon, I stood at the
magazine rack, carefully deciding on my selections.
How many comic books did I buy ?
What was the remainder ? (How much money did I have left ?)
Answer:
Step-by-step explanation:
The number of grains of wheat on the n(th) square is 2^(n-1), or 2 to
the power of n-1. This is because the first square has 2^0 = 1 grain,
the second has 2^1 = 2, and the n(th) square has twice as many as the
previous. Thus the total number of grains of wheat is
S = 1 + 2 + 4 + 8 + ... + 2^63.
Since this is a geometric sequence with common ratio 2, the sum is
2^64 - 1
S = -------- = 2^64 - 1 = 18446744073709551615.
