temperature dropped from 4 degrees to -18 degrees, how many degrees did it drop

all you have to do is count 4,3,2,1,0,-1,-2,-3 and so on until you get to -18 and then you have your answer

To find the difference in temperature, we need to subtract the initial temperature from the final temperature. In this case, the initial temperature is 4 degrees, and the final temperature is -18 degrees.

To calculate the difference, we subtract the initial temperature from the final temperature:
-18 degrees - 4 degrees = -22 degrees

Therefore, the temperature dropped by 22 degrees.
