The temperature at the base camp on Friday evening was -6°C
The temperature at a mountain base on Thursday = -2°C
On Friday morning, the temperature was 1 degree Celsius lower than what it was on Thursday, hence:
The temperature at a mountain base on Friday morning = -2°C - 1°C = -3°C
By Friday evening, the temperature was 3 degrees Celsius lower than what it was that morning.
The temperature at a mountain base on Friday evening = -3°C -3°C = -6°C
The temperature at the base camp on Friday evening was -6°C
