I have about 150 math textbooks from basic math up through Calculus. I received then from several math teachers that were retiring or decluttering. Some are like new some are gently used, Are you interested in these? Is it worth my trip of 2 hours?

They did not take many of my textbooks at all. I would try eBay. I was able to sell all of them on there for a decent price

They will entertain almost any book but it's value to them is relative to demand. In this case, I would estimate that newer text books would have a greater value as math texts are not heavily sought after by collectors. Call the store directly before you go
