Definitely algebra!! Gave me such a headache.

After reading the posts so far, I think many people are getting the concept of "useless" subject and "least favorite" subject mixed up.  Like others have stated, people use mathematics in their everyday lives and just don't realize it.  If you look for deals, or try to figure out how many items you can purchase with a set dollar amount - that's algebra and trigonometry folks (trig is simply algebra "light").  Ever re-arranged your room, put groceries away in your cabinet, do landscaping, or packed your car - that's geometry at work.  You a fan of fast cars and want to know which has the best acceleration - that's calculus.  You may not work the equations on paper, but you are using the concepts all the time.  It may have been your least favorite subject, but it's far from a useless subject.

For me I've probably used both actual information learned and/or conceptual thinking learned from every subject I've ever taken.  Even classes like the History of the Soviet Union in college.  I never took shorthand (which was mentioned above), but that might have been the only one I may have considered useless...but knowing me, I probably would have taken the opportunity of taking the shorthand concepts and created my own "language" from it just for fun.
