Yo this is fukking with my head, is it 9 or is it 1

That's not how I was taught. When it comes to Multiply and Divide, you do whatever is left most first. Same with addition and subtraction. I've never heard a rule where you multiple first just because it's first.

You were taught wrong them.

It seems as though the answer depends on which way you look at the problem. But we can't have this kind of flexibility in mathematics; math won't work if you can't be sure of the answer, or if the exact same expression can be calculated so that you can arrive at two or more different answers.

To eliminate this confusion, we have some rules of precedence, established at least as far back as the 1500s, called the "order of operations". The "operations" are addition, subtraction, multiplication, division, exponentiation, and grouping; the "order" of these operations states which operations take precedence (are taken care of) before which other operations.

This is an example of when people only know things by memorization instead of understanding what they're memorizing.

Pemdas doesn't mean you have to rigidly carry out the operations from left to right based on the acronym( multiplication before division and addition before subtraction). The order of operation is from left to right; however, as has been mentioned, multiplication and division are on the same level, so if division happens to be on the left and multiplication on the right, you do division first then multiplication. Same goes for subtraction and addition.

PEMDAS isn't the problem, it's the understanding of what to do when you're faced with both multiplication and division and/or addition and subtraction in a problem. I was taught you move left to right, others claim they were taught to do multiplication first.

I learned the same way. Haven't thought about this shyt in years

edit: beat to it

It's PEMDAS

It is 9 tho

No clue why the internet so stumped over an equation you can simply Google, talk about ass backwards.

No, you interpreted your lesson incorrectly. This is taken from the link you posted.

1. Parentheses (simplify inside 'em)
2. Exponents
3. Multiplication and Division (from left to right)
4. Addition and Subtraction (from left to right)

Everyone learned the same way, some of us remembered and others just do what they want.

Breh what the fukk is this supposed to prove other than that you're wrong? You said its 1 and calling people "dumb motherfukkers". Did you even read what you posted?

The very next paragraph explains why it would be 9 in this situation.

"When you have a bunch of operations of the same rank, you just operate from left to right. For instance,15 ÷ 3 × 4 is not 15 ÷ (3 × 4) = 15 ÷ 12, but is rather (15 ÷ 3) × 4 = 5 × 4, because, going from left to right, you get to the division sign first."

You guys are right.

Multiplication and Division hold that same weight. The order is interchangeable.

9
