We learned the Identity Property of Multiplication in lesson 3.7. It states that the product of any number and 1 is that number. The Identity Property of Multiplication can help us divide by 1. We also learned the Zero Property of Multiplication in lesson 3.7. It states that the product of 0 and any number is 0. The Zero Property can help us divide by zero. We talk about why 0 cannot be a divisor. We discuss the two rules for dividing with 1, and the two rules for dividing with 0. We see that we can use multiplication to check if we did our division correctly.
