Week 4...

This week was pretty smooth-sailing. I liked the paper-folding "social-engineering" experiment Professor Heap had in last Friday's lecture - even though I didn't bother making new friends(lol). Being able to interact with the problem through an actual experience help me remember or understand a concept waaaaay more than just sitting and listening, you can dissect the problem yourself and feel pretty darn well satisfied about it.

I found this week's concepts on proofs and using manipulation laws with symbols pretty straight forward because it involves basic math operations. The only things I am stuck on for this week are translating some key English words to symbols. The word "unless" is always equivalent to the logical "iff-not"?

And for question 6 of the practice questions on the course website, states that

For the 6.b) how is the value of x dependant on the value of x^2 being even such that x^2 => x since

x^2 = x * x wouldn't it be more likely to be dependant on the value of x being even valued rather than x^2?
