-15< -8< -2< 0< +4< +12
 * A. Arrange the following temperatures in order frooom lowest to highest:**

1. rises 10=** 15 F **2. Falls 2=** 3 F **3. falls 10=** -5 F **4. rises 7=** 12 F
 * B. The temperature reading on a thermometer is 5** **F. tell what the new reading will be if the temperature


 * C. the temperature reading on the thermometer is -5 F. tell what the new reading will be if the temperature**
 * 1. falls 3=** -8 F **2. rises 3=** -2 F **3. falls 10=** -15 F **4. rises 10=** 5 F


 * D. in 1-6, give the temperature halfway between the two given temperatures.**
 * 1.** 5 F
 * 2.** 5 F
 * 3.** -5 F
 * 4.** -10 F
 * 5.** 0 F
 * 6.** -11 F

1. < 6 2. = 3. <-5 4.< 5
 * E. in 1-4 tell which temperature reading is farther than -2.

F. explain how you determined your answer for part 4 of question E.

Well its different for each person some need to use a numberline, some just see it in there head and calculate it, some subtract and add. I happen to do a mix of those three.**
