Mathematicians agreed on an order of operations for the same reasons that Biologists came up with a system for naming species: To prevent confusion and miscommunication.
Consider this example:
ex1. 5 + 4 x 8 = 9 x 8 = 72
ex2. 5 + 4 x 8 = 5 + 32 = 37
Ex2 is correct. There's a big difference between 72 and 37. Having the order of operations laid out prevents confusion.
If someone wants 5 + 4 x 8 to equal 72, then they can write it:
(5 + 4) x 8 = 72
who are mathematicans in fiji
Both.
Archimedes
It has nothing to do with agreement or negotiation. There's only one order of operations that leads to the correct outcome.
Mathematicians use graphs to illustrate information.
There is no operation for a single number and so there can be no order of operation.
