You must, for your benefit, make an honest effort to solve the problems without first looking at the
solutions that follow. It is recommended that first you go through and solve those you feel that you
know. For the exercises that you are uncertain, review this chapter and try again. If your results do
not agree with those provided, look over your procedures for inconsistencies and computational
errors. Refer to the solutions as a last resort and rework those problems at a later date.
