The initial noon temperature is 4. Since it drops by 15, we subtract 15 from 4. The mathematical calculation is 4 minus 15, which results in a midnight temperature of -11 degrees Celsius.
The temperature in the high-altitude desert of Ladakh is recorded as 4 °C at noon. By midnight, it drops by 15 °C. What is the midnight temperature?

The recorded temperature at noon in the high-altitude desert of Ladakh starts at 4 degrees Celsius. To find the new temperature after a drop of 15 degrees Celsius by midnight, we must subtract 15 from the initial value. Setting up the arithmetic expression gives 4 minus 15. Calculating this integer operation yields a final value of -11. Therefore, the temperature at midnight is -11 degrees Celsius.
