If you were asked to send a written rule to a really smart young person learning this for the first time, what would you write to them?

• \(2\cdot 4=8\)
• \(-3(-5)=15\)
• \(10(10)=100\)
• \(1\cdot 0=0\)
• \((7)(-7)=-49\)
• \((-4)(9)=-36\)

These are all correct. What's the pattern?

• \(\frac{30}{5}=6\)
• \(\frac{-30}{15}=-2\)
• \(\frac{2}{4}=\frac{1}{2}\)
• \(\frac{4}{-2}=-2\)
• \(\frac{-14}{-7}=2\)
• \(\frac{-14}{2}=-7\)
