i just want everyone to know how to ACTUALLY do PEMDAS. Parenthesis first, Exponents second. that part is easy. but here's where people get it all wrong (or rather, it's taught wrong). it's not Multiplication third, Division fourth, Addition fifth and Subtraction sixth, it's Multiplication and Division third and Addition and Subtraction fourth. once you take care of the parenthesis and exponents, you just move left to right like you are reading. so 8/2(2+2) becomes 8/2(4). which becomes 8/2x4, which becomes 4x4 which is 16.

I'm convinced that this is a legitimate operation by another country's intelligence agency, to see how intelligent we are.

For those who don't know, it's shoeonhead's response to those people who "called her out" on her video about male loneliness.

Please note that PEMDAS is a very, very very short version of the real convention on mathematical symbols and their usage (ISO 80000-2)i just want everyone to know how to ACTUALLY do PEMDAS. Parenthesis first, Exponents second. that part is easy. but here's where people get it all wrong (or rather, it's taught wrong). it's not Multiplication third, Division fourth, Addition fifth and Subtraction sixth, it's Multiplication and Division third and Addition and Subtraction fourth. once you take care of the parenthesis and exponents, you just move left to right like you are reading. so 8/2(2+2) becomes 8/2(4). which becomes 8/2x4, which becomes 4x4 which is 16.

The obelus (division sign) is not to be used (since early 20th century), and the multiplication sign should not be omitted in case if an ambiguity. Thus, it's not that both answers are true / false, is that the equation is invalid if you want to apply today's standard. If not, then both answer are right. That's why we have the iso convention : to avoid this type of situation.
Now, it's a convention, math is a living language and can change/adapt overtime.

This has been hashed out for years. It’s simply written in a bullshit way to purposely create internet discussion.i just want everyone to know how to ACTUALLY do PEMDAS.

Due to the way it’s written the answer can be 1 or 16. As people have noted on that Reddit post and elsewhere, no one (should) ever present that problem as it’s written. It’s purposely ambiguous. Details inside. Even some calculators will tell you 1 while others say 16. It’s BUNK.
Here’s Bunk:
