Technically you could rearrange this to have almost anything you want on either side if you keep the equation equal, a better way to express this would be something like ♾=0, incorrect bur at least you couldn’t rearrange it anyway you want (and yea I understand some people say all the negative numbers plus all the positive numbers equals infinity eg. ♾= …-3, -2, -1, 0, 1, 2, 3… =0. But trust me when I say that is wrong.)

I think I spent way too much time focusing on how close these scientists were to the blackboard.

I thought it was an eyesight joke or something

It all comes to naught, in the end.:-P
