          Reverse the operations.  42 ÷ 3 = 14. 14 - 8 = 6. 6× 4 = 24

              MCM, this isn't a story problem, though, and I know you could do it. With story problems, one has to weed through what they NEED to know against the extra stuff thrown in to confuse.

              Nicole Stott is engaging intelligent down-to-earth no pun intended and link overall just an amazing person. Her stories from how she got interested in space flying to passing time staring at the Earth for hours from the International Space Station are fascinating. She also is an Omega Ambassador naturally and discusses all the ways she link used her watch link while in space.
