Excerpt: In mathematics, 1 ? 2 + 3 ? 4 + is the infinite series whose terms are the successive positive integers, given alternating signs. Using sigma summation notation the sum of the first m terms of the series can be expressed as The infinite series diverges, meaning that its sequence of partial sums, does not tend towards any finite limit. Nonetheless, in the mid-18th century, Leonhard Euler wrote what he admitted to be a paradoxical equation: A rigorous explanation of this equation would not arrive until much later. Starting in 1890, Ernesto Ces ro, mile Borel and others investigated well-defined methods to assign generalized sums to divergent series-including new interpretations of Euler's attempts. Many of these summability methods easily assign to a "sum" of after all. Ces ro summa...
