Very few of the maths textbooks I've read have had the answers to the exercises in them. Well it's been a while - by my recollection is that (at fresh and sophomore level at least), the better textbooks always did have answer keys in the back (at least for a significant subset of the problems). But as we all know -- the better textbooks are few and far between. And college is filled with lousy textbooks that get thrown at students for who knows what reasons. To the extent that they think lousy textbooks are the norm.
