Adding and Subtracting
The answer must have as few decimal places as the numbers being added or subtracted.
Ex. 6.234+2.12+3.4=11.8
You have to be sure to round the answer to the least decimal place.
The same rule applys for subtracting Significiant Digits.
Multiplying and Dividing
1. Note the measurement or factor with the least Significant Digits.
2. Calculate as normal.
3. Round the final answer to the number of digits.
Ex. (3.22m)x(2.1m)=6.762 correctly written as 6.8m^2
Following that we got a review sheet for the test on Friday and just worked on that until the bell.
The person responsible for Thursday, September 15 blog post will be Jessica Hilgers.
