PEMDAS Math Problem (Algebra Problem that Most People Get Wrong!) #shorts #maths #mathtricks

In this video I go over a Viral Math Problem that most People Get Wrong and explain how to solve it correctly by properly using the Order of Operations or PEMDAS. And even though this problem looks very simple over 70 percent of people get it wrong.

Sharp and Casio calculators use PEJMDAS, properly placing a higher priority on the juxtapositional multiplication. Which will give the correct answer of 1.
Mathematics was created in order to communicate explanations of physics, astronomy, and finances. The solution to these issues is to verify the techniques against experimentaly verifiable results and make sure that your math actually serves it's original purpose.
In science, hypotheses are tested before being accepted, let's test the hypothesis of being able to preform this math problem as proposed.

One such experiment involves rolling a wheel along a track.

Distance divided by circumference is equal to the revolutions required to roll a wheel. Dist÷2πr=revolutions.
To roll a wheel 120" how many revolutions will a wheel, with hub radius of 11", and a tread thickness of 1" have to complete?
120"÷2π(11"+1")=?
120"÷(2π)(11"+1")=?
120"÷π(22"+2")=?

Will it be 120"/2 x π(12") = ? 2262in²
Or 120"/6.283 x (12")= ? 229.2in²
Or will it be 120"/π x (24")= ? 916.7in²

Obviously not since every one of those results, to the same problem, returns a different incorrect answer with the units of inches².
Any answer much different from 1.59 revolutions is going to be incorrect. This is verifiable experimentally

PEMDAS was not "invented" by mathmaticians. It was created by grade school teachers of Mathematics, not even physics or science. It's an oversimplification to make it easier to get the basics taught. The Style Guides of both the Society for Mathematics and the Society for Physics recognize the importance of the PEJMDAS conventions that prioritizes juxtapositional multiplication ahead of division. And our experiment supports this. In science, it only takes one example to disprove an hypothesis, which I believe has now been done.
