math is for lazy people..
once you figure things out, you've figured things out...
there are two ways of going about math.. the unimaginative way,
and the imaginative way..
the unimaginative way is to brute force your way through and you
will get the answer.. it is unthinking, brutal, straightforward,
not the prettiest thing around...
the imaginative way is to find that beautiful way there, like a
dance..
both ways require you get your basics right..
