find the change in temperature minus 8 degree celsius to 13 degree celsius

21?..

To find the change in temperature from -8 degrees Celsius to 13 degrees Celsius, you need to subtract the initial temperature from the final temperature.

Change in temperature = Final temperature - Initial temperature

Change in temperature = 13°C - (-8°C)

To subtract a negative number, you can change the sign and perform regular addition:

Change in temperature = 13°C + 8°C

Change in temperature = 21°C

Therefore, the change in temperature from -8°C to 13°C is 21 degrees Celsius.

To find the change in temperature, you need to subtract the initial temperature from the final temperature.

Change in temperature = Final temperature - Initial temperature

In this case, the initial temperature is -8 degrees Celsius and the final temperature is 13 degrees Celsius.

Change in temperature = 13°C - (-8°C)

To subtract a negative number, you can rewrite it as addition:

Change in temperature = 13°C + 8°C

Now it's a simple addition:

Change in temperature = 21°C

Therefore, the change in temperature from -8 degrees Celsius to 13 degrees Celsius is 21 degrees Celsius.
