The temperature at a mountain base camp was −4 degrees Celsius on Saturday. Sunday morning, the temperature was 2 degrees Celsius lower than what it was on Saturday. By Sunday evening, the temperature was 1 degree Celsius lower than what it was that morning. What was the temperature at the base camp Sunday evening?

Respuesta :

Well when you go lower with negatives the number gets bigger so
It was -4C then it was 2 lower which is -6C then it got lower again in the evening by 1 degree celcius which gives the answer -7 degrees celcius
The equation you can use for this problem is -4 - 2 - 1

-4 - 2 - 1
-6 - 1
-7

The answer is -7
