In this Section:
In this section, we learn how to subtract with integers. We will start our process by utilizing a number line. This will give us a visual representation of the subtraction operation when integers are involved. Once this is done, we move on to a more traditional method. We learn how to convert a subtraction problem into a related addition problem. If we are looking at a problem such as: 5 - 4, we can rewrite this as: 5 + (-4). In both cases, the answer is one. So moving forward, we will leave our first integer unchanged, change the sign from subtraction to addition, and then change the number being subtracted away into its opposite.
