At six a.m, the temperature outside is 12 degree celsius. By noon, the temperature is 5 degree celsius warmer. What is the temperature at noon?

12 + 5 = ?

To find the temperature at noon, we need to add 5 degrees to the temperature at 6 a.m.

So, 12 degrees Celsius + 5 degrees Celsius = 17 degrees Celsius.

Therefore, the temperature at noon is 17 degrees Celsius.
