Question #12 in section 2.2
I drew a picture to represent the question so I could understand it better.
Ex:
A) Write an expression using rational numbers to represent the length of the pelican's dive.
Answer: 3.8 - (-2.3)
Since it's asking the length of the pelicans dive (how far it traveled) you need to start of with it's starting point which is 3.8. Then you need to add how far it went down which was 2.3 below water (-)
B) How long is the pelicans dive?
Answer: 3.8 - (-2.3) = 6.1 meters.
1) Line up the numbers properly, one on top of the other
2) Add the numbers up
3) Place the decimal in the right place
4) Remember the sign rules (+) (-)
The pelican dived a total of 6.1 meters
