You add as normal , pretend as if the signs weren't there,but the answer will be a negative!

Name the rule for dividing integers with different signs?
The value of the quotient of two integers with different signs is the same as if the signs were the same. Because the numbers have different signs, the quotient is negative.
What is the difference between subtracting with regrouping in whole numbers and subraction with regrouping in fractions?
We look at the signs of numbers when we need to combine them. We subtract only if numbers have different signs, otherwise we add them. So that, if we have in an expression several positive and negative numbers, we prefer to group numbers with the same sign and add them in order to subtract just once. While with fractions we like to group fractions with the same denominator first, and after that we can combine all fractions by finding their LCD.
Two numbers that have the same absolute value but different signs?
If you are talking about same numbers but different signs then there are a lot. such a l-4l = l4l because they are the same amount of space to the zero.
How do you add and subtract negative and postitive numbers?
