Subject: Why is there a seperate Math class?

Why does everything have to be Math.<func>(num)?  Isn't num.func more 
object oriented-ish?

For example:
 >> (Math.methods - Object.methods).select {|x| Math.method(x).arity == 
1}.each do |x|
?>     Numeric.class_eval { ?>       define_method(x.to_sym) { 
Math.send(x.to_sym, self) } >>     }
 >>   end
=> ["tan", "frexp", "sinh", "exp", "acos", "tanh", "log", "asin", 
"acosh", "cos", "log10", "atan", "erf", "asinh", "sin", "sqrt", "cosh", 
"erfc", "atanh"]
 >> *5.sqrt*
=> 2.23606797749979
 >> *Math.sqrt(5)*
=> 2.23606797749979
 >>

I think the first one, 5.sqrt, looks much better than Math.sqrt(5).

Thanks,
