Understanding Multiplication
The teacher said to the student, “Multiply [latex]3 \times 7[/latex].“
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 [latex]3 \times 7[/latex] 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.
