Ok so u see it says
"−5 degrees Celsius on Wednesday. Thursday morning, the temperature was 2 degrees Celsius lower than what it was on Wednesday. By Thursday evening, the temperature was 1 degree Celsius lower than what it was that morning. "
All of this is showing a decrease. "−5 degrees " "2 degrees Celsius lower" and " was 1 degree Celsius lower"
By knowing that its just a simple thing of subtracting how much the temp lowered over the days
\[(-5) - 2=-7\]
\[(-7) - 1=-8\]
-8 being your final answer
