An odd number is an integer of the form 2*n+1 where n is an integer. Equivalently, an odd number is an integer which leaver a remainder of 1 when divided by 2.
the answer is in math text books or on the computer.
In mathematics (number theory specifically), the definition of an even number is as follows: An integer n is even if there exists an integer m such that n = 2m. Put in more simple language, a number is even if you can divide it by 2 and get a remainder of 0. So, is 0 even? Let's see if the conditions of the definition are satisfied: Is zero an integer? Yes. Does there exist an integer m such that 0 = 2m. Yes. That integer is 0. Alternatively, let's look at the simplified definition: Can you divide 0 by 2? Yes, the answer is 0. Is the remainder 0? Yes. By any mathematical definition, 0 is even. Please do not confuse the fact that 0 is even with the fact that 0 is neither positive nor negative. The two are unrelated. The definition of "evenness" does not require a number to be positive or negative. And, yes, to a mathematician zero is a number and an integer. Please take a moment and read the article in the "Related Links" section called "The Evenness of Zero."

The definition of a node as it is used in math is that a node is a singular point of a curve. It is also defined as vertex in a graph.
