Friendly Homework 103

I think the 4th Tactic on Friendly Homework 103 is the same as a previous Friendly Homework exercise.

And the 5th!

Also true for excercise number 7.

All of pages two and three are the same as 102.

In summary, I think HW 103 replicates HW102 for Tactics 4-6 + entire pg. 2 & 3
