Yeah, as a 73 year old I got it right pretty much in my head. I try to work problems in my head or by writing them out if too complex rather than use a calculator. We also taught our kids to work math problems out by hand rather than use calculators, even though their teachers allowed calculator use.

Is PEMDAS local to your area or new? I always learned math with BEDMAS (Brackets, Exponents, Division, Multiplication, Addition, Subtraction) I only heard PEMDAS in the last year or two long after I finished school maths. Some channels here equate the two and mention both, other just BEDMAS but your channel is unique with just this PEMDAS. It begs the question is this a local thing?

@SmartAlec86 23 дня назад

Admittedly, I did get the answer wrong the first time (when I was just looking at the thumbnail) because my brain interpreted 4/8 the wrong way, which I assume is why most people get this wrong. I originally thought 4/8=2. But then I corrected myself, getting 4/8=0.5. And then 2*4=8. That's 0.5/8, or 1/16. So the answer is C. I also don't know how to put it into a calculator to get a wrong answer. [EDIT] Okay, I see how people would get it wrong. They would forget the use of parentheses.
