Using the diagram, rewrite π minus two π plus π without the brackets.

In the first diagram, they took the whole length π and then subtracted π plus π twice, so minus two times π plus π. That means weβll do the same thing. Weβll start with π and subtract π and then subtract π again and subtract π and then subtract π again. Now our goal is to write this without brackets. Weβve done that, π minus π minus π minus π minus π.

However, we can simplify a little bit without using brackets. π minus π could be rewritten as minus two π. The same thing for π minus π. We can rewrite that as minus two π. Bring down the π. And we have π minus two π minus two π. We started with π minus two times π plus π. And in this form, we distribute the negative two to the π and the π, π minus two π minus two π.
