One of the key concepts you have explored so far is the importance of consistency. Whether you are following the order of operations to solve a math problem or driving on the right side of the road to get to class, you are using a consistent strategy to get the job done. Name three other examples you can think of in the world around you where a consistent behavior or problem-solving strategy is important. If some people didn't follow the rules in each of your examples, what consequences would follow? Why is the number zero so important in our math system? How would our math system be affected if there were no such thing as zero?
