Math skills

All right, I'm no mathematician, but if I rummage through the remains of my 1st grade brain, I seem to recall that 16 is less than 20, which is less than 24. Have I been severely misinformed or have I been living in a self-created delusional world where 24 is greater than 16? I don't know which it is, but it simply has to be one of the two. Otherwise, I would not find myself continually disappointed when I reach into the variety pack box of Quaker granola bars only to pull out yet another oatmeal raisin bar. I mean, the box plainly states: 16 oatmeal raisin bars; 20 peanut butter chocolate chip bars; and 24 chocolate chip bars. Why is it that if there are truly 24 chocolate chip granola bars, I can never sink my teeth into one? Perhaps my roommates have been sabotaging me because they know that chocolate chip is my favorite. Come on, everybody knows that.
