What are the rules of integers in addition?

Rule: The sum of any integer and its opposite is equal to zero. Summary: Adding two positive integers always yields a positive sum; adding two negative integers always yields a negative sum. To find the sum of a positive and a negative integer, take the absolute value of each integer and then subtract these values.

What are the four rules of maths?

• When subtracting positive numbers, count to the left.
• When subtracting negative numbers, count to the right.

Does adding two negatives make a positive?

When you have two negative signs, one turns over, and they add together to make a positive. If you have a positive and a negative, there is one dash left over, and the answer is negative.

What are the rules of sign numbers?
