*The teacher said to the student, "Multiply *\(3 \times 7\).*"*

*The student replied, "But I don't know how to multiply."*

*Then the teacher asked, "Do you know how to add?"*

*The student replied, "Sure, that's easy."*

*Then the teacher said, "Well, then, you can multiply. Just add three sevens together!"*

*The student marveled at this notion. The student simply added 7+7+7, and answered, "Is *\(3 \times 7\)* equal to 21?"*

*The teacher said , "Yes! I knew you could multiply. I'm very proud of you."*

*The student was proud too...and very happy.*
