No.

When you have parenthesis right AFTER a number in an equation, whatever operations are inside them get done 1st and the parenthesis gets replaced by a "*".

After this, the standard order applies where "*" and "/" have the same priority, with whichever appearing 1st being executed 1st.

As such, and in the example @ hand:

6 / 2 (2+1) =
6 / 2 (3) =
6 / 2 * 3 =
3 * 3 =
9

the answer depends on whether or not you're allowing implied multiplication to have a higher priority than explicit multiplication

when solving equations by hand, people often prioritize implied multiplication over explicit:

a = 3
x = 6 / 2a = 6 / 6 = 1

but no programming language that i know of - and not even wolfram alpha - gives implied multiplication priority over explicit

and implied is normally only respected if you're using at least 1 variable in it. it doesn't make sense to write it without a variable.

so in reality, the answer is 9

an answer of 1 might have a case only if they did something like 2a instead of 2(2 + 1). but almost no math parser is going to respect the implied multiplication, except maybe that one calculator in the picture.

dude...hello? "implied parenthesis"?

hello?

you weren't summoned here to do math, you were specifically summoned here to back me up with your literal braintrap of treasured ATOT lore, with links and everything!

....and look up there, man! look up there! They're already getting angry!! I can't keep this up forever!!

I don't know what to tell you man, but when you see parentethicals like that next to a "neighbor" multiplier, you just do that whole operation first, because the outer brackets are implied in this situation. It's just how PEMDAS works. and I mean, hello! you gotta do all the multiplaction first, bro. hello! It's MD; not PEDMAS. Hello!

do you even math, bro? pshhh.

In the example above, "2a" is the same as having "(2*a)", which is why it's performed 1st and why it's result would have been "1".

Also, @zinfamous :

Notice how the calculator places it: "(6/2) (2+1)".
