    Calculus Anton or Stewart

    I would suggest Lang a first course in calculus.I learned calculus from scratch with this book and it was a very fluid read.I skipped the first part of the book and started with the Differentiation section.

    How well do you know the multiplication table?

    Guess I know them by heart if both factors are 11 or lower.If one factor is 12 I might have to do the calculation in a split-second, but that's still different than "knowing it by heart".After that I either do it in my head or use a calculator depending how hard it is and how sharp I feel.

    What do you need most in your life?

    Voted Courage, Confidence, Motivation, Hope, Passion and Sleep. Strenght is unclear to me, is it physical strenght? If it is then I don't think it's crucial.Love is also unclear, I assumed it was meant as love between a man and a woman and not as parent love in childhood, with the first one...

    Pressing fingers to nose and forehead help concentration?

    I've read somewhere that when you're concentrating on something you might stick your tongue out and apply pressure on your lip with it, and it signals to others that you do not want to be disturbed.Don't know if it's based on anything, I didn't manage to find it back with a quick google search.
