Subtracting Real Numbers

This lesson covers how to subtract real numbers (positive and negative numbers).  Before a student watches this lesson video they want to master the lesson on adding real numbers.  The reason is we change all subtraction problems (with real numbers) into adding problems- so the rule to add real numbers will apply.  Students will also want to pay special attention to the phrase  “plus negative” as it’s the method we change subtraction problems into addition problems.
