APPENDIX 1

The absolute difference between any two numbers is always a positive number. To achieve it, always subtract the smaller value from the larger value.

To find the change in temperature, calculate the absolute difference between the two temperature values.

Example:

initial temperature = 56°F
final temperature = 126°F
temperature change = final temperature – initial temperature
  = 126°F – 56°F
  = 70°F
