This is a college textbook, and that explains how to solve it

It's a college refresher course on high school Maths. They also forgot to cover The Distributive Law, which is not unusual given college Professors don't actually teach high school Maths.

Another example

From the same refresher course πŸ™„

Alternatively, here is another example

Which also doesn't cover The Distributive Law, which isn't surprising given that chapter isn't even about order of operations! πŸ˜‚

In case you can’t find the correct part

Still not about a(b+c). You lot are investing so much effort into such an obvious False Equivalence argument it's hilarious! πŸ˜‚

Don't move the goalposts. I've posted textbooks showing that "solving brackets" only applies to the inside, and distribution is part of multiplication and optional.

You've said yourself your magic rule is taught in highschool, so a refresher course in college would never ignore it.

Now instead of giving weak excuses, provide your part of the proof. And I'm not talking about multiplication, I want to see anywhere where a distribution is given precedence over an exponent.
