@mefujimori commented on previous version: Very nice - I just take issue with calling negative four "minus four". This confuses middle school students who are trying to learn the different meanings of the dash symbol: minus (the arithmetic operation), negative (the direction characteristic of a number), and the opposite of (as in -(-x-5), "the opposite of the quantity x minus five")
Response: Thanks for comment! Corrected with "negative" instead of "minus".
