It might help to imagine if you flip your arguments:

length [23, 34, 45] / 6 :: Int

How do you represent 3/6 as an Int?

Hi,

Prelude> :t (/)
(/) :: Fractional a => a -> a -> a

Prelude> :t div
div :: Integral a => a -> a -> a

Prelude> 6 / length [23,34,45]
error

Prelude> 6 / 3
2.0

Could somebody explain to me why this is?

thanks,

Alexander Chen
