Which method do you like better?

If you like the number line, it might help to think of positives as hot and negatives as cold.

When we + hot (or a positive number) to something, it gets warmer.
When we - hot from something, it gets colder.
When we + cold (or a negative number) to something, it gets colder.
When we - cold from something, it gets warmer.
