Will asked:
The identity property entails: 0 + A = A
The identity property of multiplication entails: 0 * A = 0
The identity property entails: 0 + A = A
The identity property of multiplication entails: 0 * A = 0
Adding 0 to a term results in the same term. Multiplying zero by a term results in 0.
Are there any practical applications to this property? In other words, in what instance would you use this property? I realize that you would use it simply when you add or multiply by zero. But, are there any other algebraic applications?
Thanks.
The practical application is when you have a dozen cans of beer and each one is empty, you know that you have no beer left because
12 x 0 = 0
