The temperature at midnight on a cold winter night is -2 degree Celsius 12 hours later the temperature increase by 9 degree Celsius. What was the temperature in noon.

_7°C or 7° C

To determine the temperature at noon, follow these steps:

Step 1: Note the initial temperature at midnight: -2 degree Celsius.
Step 2: Calculate the change in temperature over the 12-hour duration: +9 degree Celsius.
Step 3: Add the change in temperature to the initial temperature: -2 + 9 = +7 degree Celsius.
Step 4: Therefore, the temperature at noon was 7 degrees Celsius.

To calculate the temperature at noon, we need to add the temperature increase of 9 degrees Celsius to the initial temperature of -2 degrees Celsius.

Here's how you can calculate it:

1. Start with the initial temperature of -2 degrees Celsius.
2. Add the temperature increase of 9 degrees Celsius.
-2 + 9 = 7

Therefore, the temperature at noon would be 7 degrees Celsius.

9 - 2 = ? degrees
