**Teaching the Zero Product Property: **

**Solution to the Challenge **

The question illustrates the power of multiplying by zero. Maguro simply takes the numbers you give him and multiplies them by his own number, 0, which always results in an answer of 0.

**The Algebra Concept:**

The Zero Product Property is the key to solving quadratic equations like (x - 1)(x - 3) = 0. Students learn to apply Maguro's number trick to solve a variety of complex quadratic equations.
