Abstraction makes it possible to pull out the important details and identify principles that apply to other problems or situations. When applying abstraction, it may be useful to write down some notes or draw diagrams to help understand how to resolve the problem. In the jam sandwich example, abstraction means forming an idea of what the sandwich should look like. To apply abstraction here, you would create a model or draw a picture representing the final appearance of the jam sandwich once it is made. This simplifies the details, providing a clearer image of the desired outcome. Simple tools like the Windows Paint program can be used to do this, as shown in Figure.
