V.S.
My dad helped me with my math homework all the way into my senior year of high school. I even had him help me with college math over e-mail or the phone at times. However, that's because he knew that my math abilities are only slightly more advanced than Mom's (she couldn't get past pre-algebra) and if I didn't have help I might not have gotten through school despite being advanced in everything else. I have a learning disability in that area alone and I hate the subject, although I always tried.
Mom helped me learn multiplication and division when I was 9, although she had to resort to using my fear of being slapped on the head again (she got frustrated with my inability to learn it and the result was being hit on the head; she has anger issues). I once had her help me with a project because I couldn't get the wheels on the motorcycle drawn right (I was doing a project on "The Mouse and the Motorcycle"). I also needed her help when making a family tree.
As for me, I teach and like helping people all the time, so I help with homework without doing it for them. Doing it for them would defeat the point of being a teacher. Math, however, is completely left to others unless it's the really simple stuff.
