You finally get an allowance! You put $2 away in January, $4 away in February, $8 away in March, $16 away in April and followed this savings pattern through to December. How much money do you have in 12 months?
2 + 4 + 8 + 16 + 32 +64 + 128 + 256 + 512 + 1024 + 2048 + 4096 = 8190 You also happen to be the luckiest kid in the world to have such rich parents to give such a high allowance.
