Hi,(adsbygoogle = window.adsbygoogle || []).push({});

Can anybody explain me why in the third bracket in 3.139 is suddenly a minus instead of a plus? In 3.136 it is a Plus! And it is pure substitution as far as I understand...

And I checked everything before a few times: It should be correct!

And the next crazy stuff: From where does suddenly the "i" in the numerator (3.140) appear?

Thank you :-)
