Interactive Challenge Problem — Send in responses
O.K., time to wake up the ol’ brain cells.
Here’s a little challenge problem. I’ll post the problem today, and then I’ll post the answer the next day. My thought is that this would be relevant for many kinds of people.
Teachers can use this as a fun class-opener. Homeschoolers can use it to start their math studies. And anyone who enjoys math can use it to sharpen math skills. So enjoy.
It would also be fun to see how many people get it right, so please send in your answers as comments. I will post only the correct answers.
