0+0+0+... is a series where each step adds 0(except initial)
0(+0)(+0)(+0)... combine with the property of zero, is that it doesn't alter the result of number, when its added x+0=x
With this we can conclude that each op(+0) doesn't alter the result of number before it. https://en.wikipedia.org/wiki/Additive_identity
Since the series consists of NOPs which don't alter results of previous computation and don't add extra computation with more steps, the only significant number is the initial 0.
