Today in class Mr. Paek started the class by explaining how to reach the gapps website, which is, gapps.glenbrook225.org. At the website we can work on our lab reports or any papers with our partner at the same time, by clicking on the documents button on the top left, and choosing create new and scrolling down to document.
Then we learned the sig fig rules for addition or subtraction, and multiplication or division.
The rules for Addition or Subtraction are:-
· The answer must have the same number of digits after the decimal point as the measurement with the smallest number of digits after the decimal point. Example:- 135.2 – 24.075= 111.1 à The least number of number after the decimal were 1, so the answer must ONLY have one number after the decimal point.
The rules for Multiplication and Division are:-
· The answer must have the same number of significant digits as the number with the least number of significant digits.
Example:- (48.0)(0.325)(1.02) = 15.9 à The least numbers of sig figs are 3, so the answer MUST only have 3 sig figs and numbers.
(There are other examples in the picture below)
Finally, we started to learn about Metrics stating if statements are realistic. For example:- Is a basketball players 3 meters tall? The answer would be no, because 3 meters are higher than the ceiling.
I think you did a good job on explaining how to use google apps and it was a great idea talking about the rules for sig figs! It would've been better if you put pictures with this post, but overall great job!
ReplyDeleteYou did a great job explaining what google apps is and how to use it. I understand sig figs better by reading over this blog because you explain the rules in a good way. Thanks mate!
