Rules for adding integers?
When you add: a negative and a negative: you get a negative a positive and a positive: you get a positive a positive and a negative or a negative and a positive: Subtract the addend with the smaller value from the greater one. If the greater one is positive, your answer will be positive. If the greater addend is negative, your answer will be negative.
What two numbers do you add to get 0 and multiply to get 80?
80
What are the rules for adding and subtracting integers?
when you add two positive integers the answer is always positive when you add two negative integers the answer is positive when you add one negative and on positive integer, the answer is negative subtracting two negative numbers gets a negative answer subtracting two positive numbers- the answer depends subtracting a negative and positive number- the answer depends, the positive number would have to be bigger than the negative to achieve a negative number, and if the positive number is less, than the answer is still negative
What does a positive fraction plus a negative fraction equal?
The sum will take on the sign of whichever one is greater.
Does a negative fraction plus a positive fraction equal a positive fraction?

How do you divide with a negative fraction?
Divide as you would divide positive fractions. That is, convert both fractions to positive, then do the division. After that, apply the rules for dividing positive and negative numbers. For example, if one of the fractions is positive and the other negative, the answer will be negative.
When you add numbers that have different signs will you always get a negative number?
No. When you add a positive and negative number, the bigger one determines the sign of the result. For example, when you add -5 and 3, the result will be negative because the negative number is larger. When you add -4 and 6, the result will be positive because the positive number is larger.
