1 + 2 + 3 + 4 + … ∞ = -1/12

OK – a change of focus. No politics.

Let’s encourage some interest in Mathematics – watch this Numberphile video to see the (apparently divergent) series in the title is equivalent to -1/12

Let me make it clear – sum the infinite series of Natural numbers ( 1 + 2 + 3 + 4 + 5 + … and never stop) and the approximation value which results is -1/12

A negative fraction from an infinite sum of positive numbers.

There are many videos discussing this – and versions with more complex applications of Riemann’s functions to find the same result.
