He just blurted out an equivalent answer, but it's not a
verbatim translation. Here is how to translate it verbatim:
two Less than the quotient of a number and two
Substitute "N" for the words "a number:
two Less than the quotient of N and two.
Substitute "N/2" for the words "the quotient of N and two"
two Less than N/2
To make something less you subtract from it.
So to make it *two less* you subtract 2 from it, so
you end up with
N/2 - 2.
