## What does a negative plus a positive equal?

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. … The sum of any integer and its opposite is equal to zero.

## When you divide by a negative does the sign change?

## What is a negative plus a negative?

When you are adding a negative number to a negative number, it becomes subtraction, where you start from a negative point on the numbers line and move left. For example, -3 + (-2). This reads “negative three plus negative 2”. … Then we subtract 2. The answer is -5.

## Why do 2 negatives make a positive?

Each number has an “additive inverse” associated to it (a sort of “opposite” number), which when added to the original number gives zero. … The fact that the product of two negatives is a positive is therefore related to the fact that the inverse of the inverse of a positive number is that positive number back again.

## Can negative numbers divisible?

The defintion of integers cannot exclude negatives! Moreover if any number is divided by 2 it is even. So negative even integers exist. X and Y both are prime.
