| Never got around to memorizing pi, but I did memorize the powers of 2 up to 32. It started out as a little game to kill time (in the first grade), and it went like this: 1+1=2, 2+2=4, 4+4=8, 8+8=16, but I went a bit overboard... This useless bit of knowledge helped me score a point at an interscholastic math contest ten years later. 1 Power (2,0) 2 1 4 2 8 3 16 4 32 5 64 6 128 7 256 8 512 9 ========== 1 024 10 2 048 11 4 096 12 8 192 13 16 384 14 32 768 15 65536 16 131072 17 262144 18 524288 19 ========== 1 048 576 20 2 097 152 21 4 194 304 22 8 388 608 23 16 777 216 24 33554432 25 67108864 26 134217728 27 268435456 28 536870912 29 ========== 1 073 741 824 30 2 147 483 648 31 4 294 967 296 32 |
