It is given that the temerature recorded at midnight was -2°C
In the next afternoon the temerature raises by 9°C
So the new temerature can be obtained by adding the 9°C to previous temearature reading
That is the tempearature at afternoon in the next day is,     -2°C+9°C=-2+9°C=7°CNow at 10 pm, the temearture drops by 11°C
So to find the final temperature, this temearature of 11°C must be subtracted from previous reading of temperature
Thus the current temerature is,      7°C-11°C=7-11°C=-4°C

in a hill station the temperature recorded at midnight was -2* c. if the temperature raises by 9 * c the next day afternoon and drops by 11 degree C at 10 pm, what was the temperature will it be now ?
