This was such a great read!! I haven't done work adding and subtracting signed numbers in a long time, but thinking about subtracting a negative as erasing debt makes so much sense!
Thank you so much, Kayla! Yeah, debt is one of my favorite ways to help students understand negative numbers. And number lines are a critical tool - so much more useful than any "rules," IMO!
