This part is interesting. In the last section we saw that we could \textbf{not} further simplify terms that were different such as \(2x + 4y\). But now with multiplication and division we can! \(2x \times 4y = 8xy\) and \(2x \div 4y = \frac{\cancel{2}x}{\cancel{4}y} = \frac{x}{2y}\). Isn't that cool?

Okay, now you guys try:
