There are many different ways to solve subtraction problems, and I am going to show you three ways.
The first method of solving subtraction problems that I am going to show you is the CLASSIC HORIZONTAL method. This is the simplest way to use subtraction and is commonly seen.
The next method of solving subtraction problems is the STACKING method. This is an easier way to solve subtraction problems, and is one of the most commonly used methods.
The last method of solving subtraction problems that I will show you is the SUBTRACTION BY ADDITION method. This is thought to be the easiest way of the three that I will show you. Many people use this method to feel more comfortable with subtraction, or at least until they get the hang of it and can move on to the other methods of subtraction.
Here are some pictures of the three different methods that I am going to show you:
Subtraction by Addition
