Answer
Explanation:
Step1: Analyze the expression
The expression is $- 5+(-4)$. Adding a negative number is the same as subtracting a positive number. So $-5+(-4)=-5 - 4$.
Step2: Interpret the meaning
The first number $-5$ represents the initial temperature. The operation $+(-4)$ means a decrease of 4 degrees since adding a negative is equivalent to subtracting a positive.
Answer:
The temperature was -5 degrees, then it decreased 4 degrees.
