It depends upon the scale (units) being used:
Water is its densest at about 4oC ≈ 39oF which is why ice at 0oC (32oF) floats.
- 23 degrees
Still 54 degrees if the 18 degree drop is inside!
If the starting temperature is 86 degrees Fahrenheit, and it drops by 40 degrees, the temperature is 46 Fahrenheit. It's simple subtraction.
24 degrees 12pm
When the sun goes down, the temperature drops.
- 23 degrees
generally speaking, for every 100 m (330 ft) elevation increase, the temperature drops 0.6 degree Celsius (or 1.08 degree Fahrenheit).
Precipitation will be released in the form of hail and/or rain and the humidity will remain unchanged. or The relative humidity will decrease.
Still 54 degrees if the 18 degree drop is inside!

You will recall from the Ideal Gas Laws that temperature, pressure, and volume are all connected in terms of the behavior of a gas (especially an ideal gas, but actual gas resembles ideal gas to a certain extent). So, if the gas is in a container of fixed volume, then reducing the temperature will correspondingly reduce the pressure.
If the temperature is 44F and the temperature drops 20 degrees, the temperature would be 24. Subtract the temperature drop from the starting temperature.
You need to provide a point of reference. If the temperature is 100 degrees F and drops to 50 degrees, that is still a comfortable temperature for most organisms. However, if the temperature is 50 degrees and drops to zero, many organisms would be adversely affected, especially if the temperature remained cold for an extended period.
The temperature rarely drops below 18 degrees Celsius.
If the starting temperature is 86 degrees Fahrenheit, and it drops by 40 degrees, the temperature is 46 Fahrenheit. It's simple subtraction.
