Going left to right is part of the order of operations.
Quoting: Anonymous Coward 32614604 Technically no, but it gives young students a sense of order. Adding and multiplying is associative, so it doesn't matter what order you them in. Subtracting and division are the same as adding and multiplying. It is knowing things like this, as well as other details of maths, that allow you to see that this equation is solved as 1. [ link to math.berkeley.edu] Read that. It is important to note that this stipulation about \from left to right"is entirely extraneous, because the associative laws of addition and multiplication ensure that it makes no di erence whatsoever in what order the additions or multiplications are carried out. Quoting: Brekeley.eduif it makes no difference whatsoever in what order the operations are carried out, then WHY are some people saying "1" and some people saying "9"?
