What is the multiplication property of -1

The video tutorial explains the multiplication property of -1, demonstrating how multiplying a positive number by -1 results in a negative number. It uses the example of multiplying 7 by -1 to show that the result is -7. The tutorial also highlights the commutative property, indicating that the order of multiplication does not affect the result, as shown by rewriting -7 as -1 * 7. Finally, the concept is generalized with the number 8, emphasizing that any negative number can be expressed as -1 times a positive number.
