I am a dumb, ignorant, old guy going back to school to learn math. So, I read this article and find the statement "It is possible to sum fewer than 2 numbers". Really? That seems, to me, anyway, to violate the logic of a definition of a sum; a sum means we are adding one value to another value

The sentence, as it is currently, is absolutely not ambiguous, as I do not know anybody who understand "the 100 first natural numbers" as not containing 100. Moreover, in the case of a doubt, this is clarified by the formula that follows. So, the unneeded use of a technical terminology that you

1. Many definitions, including the official standard ISO 80000-2, include 0 in the natural numbers. "Natural numbers" may or may not include 0, while "positive integers" always excludes 0. A more precise term is preferable to a less precise one. Why use an ambiguous term when an unambiguous one

You deal with sums of a single number all the time. Every time you go to a store and buy a single item, there's a line on the receipt that says "total" (er, well, "subtotal") with just the price of that one item, right? So the sum of a single item is really not an impossible concept—it's a very

A sum of zero numbers is similar. Imagine that you have a bank account into which you make no deposits for a certain month. At the end of the month you will get a statement from the bank with a line that says something like, "Total deposits $ 0.00." That's a sum of no numbers!

How about replacing "summation of the first 100 natural numbers" with "summation of natural numbers from 1 to 100"? However, in the sentence immediately after it, it says "1 + 2 + 3 + ... + 100", so I think it's clear even as it is

Which identities are wrong and what are the correct identities? Note that in the comments, "distributivity", ... do not mean that the identity makes the property explicit, but rather that this is used for proving the identity.

The sum of 1 from m to n is n - m + 1, not n - m. A trivial example, sum 1 from 1 to 10, the answer is not (10 - 1 = 9), it is (10 - 1 + 1 = 10).
