How to Divide a Negative Integer by a Negative Integer

Math with Mr. J

This concise math tutorial demonstrates the specific rules and logic for dividing a negative integer by another negative integer. The video uses a digital chalkboard format to walk students through two specific examples: -9 divided by -3 and -50 divided by -5. The narrator emphasizes the core rule that dividing integers with the same signs always results in a positive quotient. Beyond simply stating the rule, the video explores the conceptual reasoning behind the math. The narrator explains division as finding "how many groups" of a negative number fit inside another negative number, offering a tangible way to visualize the operation. This approach helps move students from rote memorization to conceptual understanding. A key feature of this video is the verification step included for every problem. The narrator demonstrates how to use the inverse operation—multiplication—to check the answer. By rewriting the division problem as a multiplication equation (e.g., "what times -3 equals -9?"), the video reinforces the relationship between operations and gives students a practical strategy for self-checking their work in the classroom.
