So kind. Thanks!
" As well you should have been. Similarly, you are expected to write in complete sentences, capitalizing proper nouns and the first words of sentences.
Mathematics courses are about methods, not answers. Sans showing steps, there is no way to tell if the student even has an idea about how to solve a problem. The student may have got the answer by working it out, hearing it on the radio, seeing the answer on a nearby student's paper, or guessing. Also, (at least in some of my courses), partial credit would be available for correct methods with some penalty for arithmetic mistakes."
No math whiz here, but it always seemed the more advanced math concepts were built upon the foundation of basic. The more complicated equations had and underpinning of less complicated individual operations. Showing work makes sense.
