Subtracting real numbers a negative from a positive, 11 - (-2)

The video addresses common student questions about negative numbers and explains the concept of additive inverse. It demonstrates how subtraction can be rewritten as addition using the additive inverse, and uses a number line to visually represent this process. The goal is to encourage students to think critically and understand the underlying mathematical principles rather than just seeking answers.

Discuss why the teacher prefers students to think through problems rather than just providing answers.
