I’m not going to add the cost of a frozen pizza to the number of cucumbers I bought before multiplying by the number of pizzas I bought and then multiplying that by the cost of a cucumber. Right; and that helps to explain _why_ the order of operations rule works the way it does. See (if you care) the posts by @Senegoid in this thread: > [@Okay, but WHY does multiplication/division come before addition/subtraction?](https://boards.straightdope.com/t/okay-but-why-does-multiplication-division-come-before-addition-subtraction/954352): > > I mean, I know it does. I know it’s Brackets/parentheses (depends where you live) Exponents/orders (depends) Division Multiplication Addition Subtraction I can see the point of having brackets, since then you can change the order, and exponents net, but why did they put div/multiply before addition and subtraction? Is there an advantage to that?
