Step-by-step explanation:

Step 1: Define

Temp [Tahiti]: 27°C

Temp [Siberia]: -33°C

Step 2: Difference

1. Set up expression:                    27°C - (-33°C)
2. Simplify:                                     27°C + 33°C
3. Add:                                           60°C

Depending which city is first, the overall difference will be 60°C. If we take the difference with Tahiti first, we would have a difference of +60°C. If we take the difference with Siberia first, we would have a difference of -60°C.
