I have read many times that FORTRAN is better Than C for number
crunching buy I do not know WHY?
Obviously I am missing some knowledge therefore can somebody please
educate me as I do not thing that FORTRAN can calculate faster than C
statement like
c = a + b
or even
c = sqrt(exp(a, 2), exp(b, 2))
so what is that makes the difference...?

Long story short, it's actually not. Once upon a time, it was, when C
was a systems programming language and FORTRAN was explicitly created
for mathematics. Now, not so much -- with the GNU tools, both
languages compile down to essentially the same thing and are
essentially equivalent in performance.
