An equation for language acquisition

I recently developed this equation that seems to account for all grammatically as well as operational input. The equation goes as such.

x = n*y(...n*y)*y

X stands for a unit of knowledge/item, n is the variable for any symbol/operation, y stands for any whole number. (... Stands for 'followed by')

How does this look as viable pseudo code? Any comments?

the equation has been updated to one of cognitive acquisition.
