Question about Reductions.

[e2041800@luna.escuelaing.edu.co]

Hello:

I am a student of computer science and a user of Hugs, I am interested to know  
How hugs calculate the 
number of reductions when evaluating an expression. I dont understand for 
example why evaluating the 
expression 9 gives 12 reductions.

Main> 9
9
(12 reductions, 18 cells)
Main>


I would appreciate if someone can help me with my question
