I am talking about the subsection Exponentiation#Exponents_one_and_zero saying: "The meaning of 35 may also be viewed as 1·3·3·3·3·3 the starting value 1 (the identity element of multiplication) is multiplied by the base as many times as indicated by the exponent. With this definition in mind, it is easy to see how to generalize exponentiation to exponents one and zero: 31 = 1·3 = 3 and 30 = 1. This leads to the following rules: Any number to the power 1 is itself. Any nonzero number to the power 0 is 1; one interpretation of these powers is as empty products. The case of 00 is discussed below." There is no justification here for restricting the second rule to nonzero numbers, and the reader, accepting the definition, is confused that the editor does not accept the conclusion. You guys who do not accept the conclusion are reponsible for making a subsection that makes sense.   .
