For additional explanation on the topic of Signed Numbers, see my own website. You can do a Bing search for my last name "Rapalje", and look for "Rapalje Homepage" at the top of the search list. For an explanation of Signed Numbers and Order of Operations, look for the link "Basic, Intermediate and College Algebra: One Step at a Time". Choose "Basic Algebra" and look in Chapter 1 for these sections near the beginning of the chapter. See also the "MATH IN LIVING COLOR" solutions for many of these exercises--IN COLOR!!
