The rule is not a panacea and will not solve all your problems. in particular, if the number of choices of a certain ith character changes depending on the choices for the first (i 1) characters, then the product rule doesn’t apply. examples: (a) how many 4 digit numbers are there whose first two digits sum to less than or equal to 9?.

Introduction. the rule of sum (addition principle) and the rule of product (multiplication principle) are stated as below. rule of sum statement: if there are n n choices for one action, and m m choices for another action and the two actions cannot be done at the same time, then there are n m n m ways to choose one of these actions. rule of. 1.1. the s. m and product. ules. or sets chapter 1. basic countingchapter 1. basic countingnote. in this first chapter, we present the “most elementary techniques” for enu meration. the. techniques will increase in difficulty in the following chapters. no tationally, we denote the natural. umbers, integers, rationals, rea.
