What’s the deal introduction to real analysis bartle solutions manual pdf this orders of operation business? Q: Is there a single equation that proves black holes are real? Q: How do I estimate the probability that God exists?
Now that the Physicist and I have answered questions like these ones at least 9 times via email, I figure we should get this horrible topic out of the way once and for all with a short post. The convention has been accepted just so that when different people see an equation they can agree on its meaning, even if they hate each other’s guts. You could come up with a different convention, but why bother? Let other people waste their time coming up with arbitrary conventions so that you can merely waste time reading posts about them. Next, multiplication and division get carried out from left to right. Finally, additions and subtractions get carried out from left to right.
One interesting thing to note about the order of operations is that there is nothing interesting about them whatsoever. But that implies there is something interesting about them. This is a contradiction, and hence the order of operations form a paradox. But, that won’t stop me from giving an example. When in doubt about what the orders of operation are for an expression, there is a simple solution which works even better than tattooing PEMDAS to your face.
