Temperature Question

This morning the temperature was 12 degrees Celsius. By 12pm it had  increased by 7 degrees so it is now 19  degrees  Celsius.   By 6pm the temperature  then dropped by 5 degrees to be 14 degrees Celsius. Now at 8pm, it has dropped 3 more degrees, so  the  new temperature is 11 degrees  Celsius.                 The Equation (what are the numbers?)

12+7-5-3=11
