## What is the rule for multiplying and dividing positive and negative numbers?

With two numbers, the rules for multiplying and dividing positive and negative numbers are not only simple, but they’re also the same for both operations: When multiplying or dividing two numbers, if the two signs are the same, the result is positive, and if the two signs are different, the result is negative.

## What is the quotient of two negative numbers?

## What happens when you subtract a negative from a positive?

Rule 4: Subtracting a negative number from a positive number—when you see the subtraction (minus) sign followed by a negative sign, turn the two signs into a plus sign. Thus, instead of subtracting a negative, you’re adding a positive, so you have a simple addition problem.

## What is the rule for adding and subtracting integers?

To add integers having the same sign, keep the same sign and add the absolute value of each number. To add integers with different signs, keep the sign of the number with the largest absolute value and subtract the smallest absolute value from the largest. Subtract an integer by adding its opposite.

## What are the rules for adding subtracting multiplying and dividing positive and negative integers?
