An understanding of numbers plays an important part in our daily lives and even more so as our society advances technologically. No one expects to look out a window and to think about the numerical structure of what we see, just as we don't picture the molecular structure of water as a boat floats by. Yet knowing how to use the mathematical tools at our disposal can help us function much more effectively and also enhance our critical thinking skills.
