The temperature at 6:00 am was -12 degrees. By 3:00 pm, the temperature was 27 degrees. What was the change in temperature between 6:00 am and 3:00 pm?

27 + 12 = ?
27° - (-12°) = 39° change in 9 hours

Became curious what the greatest change per day in history was, so ....

The largest recorded temperature change in one place over a 24-hour period occurred in Jan 1972 in Loma, Montana, when the temperature rose from −47.8 to 9.4 °C , a change of 57.2° C

The most dramatic temperature change occurred in Pincher Creek, Alberta in Jan 1962, when the temperature rose from -19° to 22° C in one hour or 41° in one hour.

The stuff you don't learn on Jiskha!
Wow! That reminds me of a popular newspaper columnist many years ago. Every so often he'd write a column on "things I learned on the way to looking up other things."

Thanks, Reiny.
Fun Fact... I have visited Pincher Creek Alberta : )
