Subject: EVEN and ODD turtles... ifelse (remainder who 2 = 0)

Hello 025 students,

      http://www.cs.uni.edu/~jacobson/logo/applets/FlyFishing.html

            has some new information for you that will really help!

      THINGS TO TRY section has new info and
                    shows how to do the EVEN/ODD turtles task.

      There is extensive explanation of the following:

             ifelse (remainder who 2 = 0)

                   [ what you going to do if you are an EVEN turtle ]

                   [ what you going to do as an ODD turtle ]

             Your remainder when we divide by 2 is either 0,     EVEN
                                                                 ----

                                            or ELSE it is 1.     ODD
                                                                 ---

              who are U, tUrtle?   Every turtle has a who number
              ---                                     ---

              1 2 3 4 5 6 7 8    if you have 8 turtles, for example,

              1   3   5   7      are the ODD who numbers, ODD turtles,
            and
                2   4   6   8    are the EVEN who numbers, EVEN turtles.
