Hi,
when you write 3 Haskell sees it as a "num" while the type of the length
[1,2,3] is "int". So 3 and length [1,2,3] have not the same type.

I can divide a float by an integer
2.4 / 3 0.7999999999999999
but why can I not do this?
< 2.4 / (length [1,2,3]) <interactive>:288:1-22: error: * No instance for (Fractional Int) arising from a use of `/' * In the expression: 2.4 / (length [1, 2, 3])
