48 - fā valu (Tongan)
* This has got to be the easiest number system I know. To read numbers you just read out the digits. In the above example, forty-eight is literally just "four eight".

It is easy to go down into Hell;
Night and day, the gates of dark Death stand wide;
But to climb back again, to retrace one's steps to the upper air –
There's the rub, the task.
