We also learnt about Prefixes used with the "Le systeme International d'Unites" = Si System.
We also took notes on significant zero
1) If there is a decimal after the zero it is significant.
IE. 1020. 302980.
2) You must round to the least percise number
IE. 4212-3.54= 3.8812 S.D.s= 3.88
3) When you multiply and divide, round to the number with the fewest S.D.s
IE. 2.5x5.55= 13.875 S.D.s= 14
Near the end of class we watched two youtube videos. One of a bridge collapsing and the other a swing fail. http://www.youtube.com/watch?v=3q27dzRgHLo
