Subject: Adding and subtracting integers
Adding and subtracting integers can be a somewhat confusing concept to teach and for students to learn and master but I think once you understand the underlying reason, the rules start to make sense. Instead of explaining it here, I'm going to refer you to some great answers from our Dr. Math archive: An answer to a similar question by Doctor Sonya http://mathforum.com/dr.math/problems/tracey12.31.97.html Another answer by Doctor Santu http://mathforum.com/dr.math/problems/jaime12.1.98.html Another one from Doctor Sydney http://forum.swarthmore.edu/dr.math/problems/manne10.15.96.html I hope these pointers prove useful for you and your son.
