An integer is the number zero (), a positive natural number (1, 2, 3, etc.) or a negative integer with a minus sign (−1, −2, −3, etc.). The negative numbers are the additive inverses of the corresponding positive numbers. In the language of mathematics, the set of integers is often denoted by the boldface Z or blackboard bold.. The set of natural numbers is a …The LaTeX part of this answer is excellent. The mathematical comments in the first paragraph seem erroneous and distracting: at least in my experience from academic maths and computer science, the OP’s terminology (“integers” including negative numbers, and “natural numbers” for positive-only) is completely standard; the alternative …However, if you consider the domain to be all real numbers, it is not continuous. To be continuous at a point (say x=0), the limit as x approaches 0 must equal to the actual function evaluated at 0. The function f(x)=1/x is undefined at 0, since 1/0 is undefined.٠٨/٠٣/٢٠٢١ ...
