  1. turn the first one around
    a>2 ----> 2<a

    then 2 < a < 7

    (usually we have the smaller numbers on the left and the larger on the right, which of course means we could have < in our statement)

  2. Could you check to see if I did the next one correctly?
    2.z < 0 and z > -6

    -6 < z < 0
