Final Answer:
-12°C
──────────────────────────────────────
Explanation:
You start with 7°C. Then the temperature drops by 19°C. That means you take away 19 from 7.
Think of it like this:
You have 7 candies. You give away 19 candies. But you don’t have enough! So you owe 12 candies. That’s -12.
So, 7 - 19 = -12.
The temperature will be -12°C.

Teach the Topic:
This is about negative numbers — numbers less than zero. They’re used when we go below zero, like in cold weather or when we spend more money than we have.
Simple example:
You have 3 apples. You eat 5 apples. How many do you have left?
You ate 2 more than you had → so you owe 2 → that’s -2 apples.
Negative numbers help us show “less than nothing.”
