Which one is right?
Which one is wrong?
The functions of the calculator
Or the scholarly facts from a textbook
Either way they give an answer
Similar or not you just don’t know
Until you seek for outside source
Such as those behind the works
Even Einstein still had questions
Going beyond his own precautions
So as you sit racking your brain
Redoing the equation, make you insane
so which one is right or wrong?
The textbook or the calculator
