She said if you had a bowl of water with an ice cube in it and the temperature of the water was 3 degrees, and the temperature of the ice cube was -2 degrees, what would the temperature of the water be if you took out the ice cube? Er 5. Yippee I get it now.
Don't think the example as quoted is accurate as a physical example: perhaps how it should be phrased is "by how many degrees does the ice cube need to warm up to be the same temperature as the water ? "
Another way to look at it could be floors in a lift: you're on floor 3: how many floors down is it to the 2nd basement?
