If you have a bunch of unparenthesized addition and subtraction, left to right doesn't matter.

Right, because 1-2-3=3-2-1.

    You flipped the sign on the 3 and 1.

    I did not flip any signs, merely reversed the order in which the operations are written out. If you read the right side from right to left, it has the same meaning as the left side from left to right.

    Hell, the convention that the sign is on the left is also just a convention, as is the idea that the smallest digit is on the right (which should be a familiar issue to programmers, if you look up big endian vs little endian)

    Yes you did! 😂

    No, merely reversing the order gives -3-2+1 - you changed the signs on the 1 and 3.

    If you read the right side from right to left, it

    Starts with -3, which you changed to +3

    it has the same meaning as the left side from left to right

    when you don't change any of the signs it does 😂

    Hell, the convention that the sign is on the left is also just a convention

    Nope, it's a rule of Maths, Left Associativity.
