Metrics and Significant Figures

Friday, September 3, 2010

Today in class we received pages 7,8 & 9 to add into our composition books and discussed the homework, pages 1 and 2 in our notebooks

The next thing we did in is learn the sig fig rules

ex. zeros between non-zero digits are aways significant 3.108 is 4 sig figs

we then learned rouding sig figs
 ex. rounding to 4 sig figs - 12,345,670 would be 1235000
