anonymous
  • anonymous
subtract..?
anonymous
  • anonymous
so you're making a cake and the direstions ask you to combine ingredients. does that mean remove (or "subtract") the eggs and oil from the dry ingredients?
anonymous
  • anonymous
no doesnt it mean to add the ingrediants? since they want you "combine" the ingrediants?
anonymous
  • anonymous
exactly, but where's the confidence? now, apply to this situation. do they want you to subtract the number of students who prefer bike racing from those that prefer reading? if not, what do they want you to do with them?
anonymous
  • anonymous
they want you to add them! (confidence)
anonymous
