Lenny Maths!

Just suppose, for the sake of argument, that you have a large block of stone. While staring at this block of stone, it dawns on you that perhaps you should carve it into something. Luckily, you have a hammer and chisel handy.

But it’s no ordinary hammer and chisel. Somehow, no matter how hard you hit the chisel, exactly one-half of one percent of the block chips off.

How many times do you have to hit the chisel before the block is less than half of its original size? Click here to answer.

This one is either incredibly simple to answer (an thus won’t give much of a prize) or very long like the other math exersizes we’ve seen before. Because of this, I think it would be safe to assume that the one percent they talk about is not always 1% of the whole block, but 1% of what’s left. Taking that into account, it’s time to do some serious calculations!

Good luck!
