Good question. Tried to get everyone confused with the zero in there because everyone knows that you can't divide by zero when in fact the question deals with how far of a departure is from the temperature that you feel comfortable or the temperature that you can tolerate. So if I began to feel cold at 35 degrees (I love cool weather), and today it is 35 degrees cooler than my cold level. Therefore if I were to say that it was literally going to be twice as cold... it will be -35 degrees tomorrow. Wow now that is cold.
