You can do a method i use called "Keep Change Change" which only applys when subtracting by a negative. You keep the first number, change the sign, and change the last number. (ex. -4 - -2 = -4 + 2)
Two negatives do equal a positive. You will also convert the minus sign into a plus sign so it would end up being 4 + 2.
4 + 2 = 6
Guest #3, you are incorrect
I was guest number three and I was incorrect. You have to keep flip change. Instead I changed everything. It would be -4 + 2 = -2.
