I know some places use BIDMAS as well. Overall though, to someone who knows little about mathematics, why is this the correct order? What’s the exact logic behind it
In: 6
The “correct order” is one which we all agree on. Parentheses coming first makes a lot of sense, since their whole purpose is to establish the ordering of things. Pairing multiplication and division next to one another makes things a lot easier, since they are effectively the same thing and it is often easier to do them all at once. The same with addition and subtraction.
