Ever since I was a very small child I realized that fractions were much easier to work with than decimals. Later in school when I learned how to manipulate polynomials I realized that EVERYTHING I learned about fractions was applicable. However, almost nothing to do with decimals has anything whatsoever to do with polynomials. Now that I am a college professor I realize what a disservice schools are doing to America's children by allowing them to become fractionally illiterate. It is as if they (schools) are setting up our kids for failure later in their education. What is so difficult about fractions?
