What are the rules of addition?
If you mean integers, well if you have two integers of the same sign that you are adding, add and the sign stays the same. If you have different signs, subtract and keep the sign of the one that has more. Regular numbers you just add them.
When adding two rational numbers with different signs the sum will be zero Is this aways sometimes or never true?
sometimes true (when the rational numbers are the same)
What are the basic rules for multiplying and dividing sign numbers?

Adding integers, if they have the same sign, add their absolute values and keep the same sign. Subtracting, change the sign of the 2nd number and the add using rules of addition. Multiplying and dividing, Divide the absolute values, if the signs are the same the answer is positive, if the signs are different the answer is negative.
What is the rule for adding integers with different signs?
If it is two negative numbers then you add: ex: -7 + -5 = -12 If it is two different signs, then you subtract: ex: -8 + 2 = -6 Can you see which one is the larger absolute value? 8 is larger than 2 so it is negative.
