When adding a positive number to a negative number what is a good rule for determining the sign of the sum?
If the negative number is a bigger number, the answer will be negative. Conversely, if the positive number is bigger, the answer will be positive. -20+10= -10 (larger negative number) -10+20=10 (larger positive number)

What is the rule for adding 2 negative integers?
The rule is if a number is positive you add them. EX: 4+4=8 But if the numbers are both negative... you forget the plus sign and just put the numbers together and use whatever sign they have. EX: -4-4= -8 you see? you are adding them put if they are negative, they go down the number line. not up. Just picture a number line, if you add a negative number to an already negative number, wouldn't the number go to the left? The answer is yes. Yes it would. :)
