I came across this when doing another problem:(adsbygoogle = window.adsbygoogle || []).push({});

Suppose we have 2 numbers, (a+b) and (c+d), which both equal 0.

a+b=0

c+d=0

Then a+b=0=c+d,

Thus, a+b=c+d

However, a+b+c+d=0

Thus, a+b=-c-d

Therefore, a+b=c+d AND a+b=-(c+d)

How is this possible?
