Adding real numbers negative to a negative, -7 + (-5)

The video tutorial explains the concept of negative numbers using a number line. It shows how negative numbers are positioned to the left of zero, representing a distance in the opposite direction of positive numbers. The tutorial then demonstrates how to add negative numbers by moving in the negative direction on the number line, emphasizing that the sum of negative numbers is also negative.

What do negative numbers represent on a number line?

• A positive number

• It depends on the numbers

• A negative number
