It should be noted that this feature makes teaching math to people who ask, "Why do we have to learn this? When will we ever use it?", rather difficult.

The best overall answer I've seen is along the lines of, "Because it makes your brain stronger and more flexible, and teaches you to think logically, better than anything else", which is a sound argument, but not especially compelling to most students.
