he just rolled a number, basically you type *roll x* where x as a number between 1-9(number of digits you want to roll) and it generates a random number. He rolled "79" the first digit's a 7 the second digit's a 9, just insert them into the sentence, that parts not too complicated. it was pretty impressive because he could have ended up with any number between 00 and 99 so he had i 1/100 chance of rolling that a 79, pretty low odds.
mmmmm I'm not gonna go into this too much because I don't think I can be convinced to see this from any other angle.
He says division is glorified subtraction, it is not in my mind because you cannot subtract 7 from 22 with whole numbers. What happens once you need to put in that 1/7th in at the end? You can't "glorify" your subtraction to get that number.
No, division has always been a question of how many times can this number, fit into this number. 7 can fit into 22 3.142857 times.
0 can fit into any number an infinite number of times, which is why I say that x/0 is always equal to infinity.
I see it as subtracting the number by itself until it reaches zero, then counting the iterations. But that's not the point.
I think, in the video, he meant that since multiplication is sequential addition, and subtraction is the opposite of addition, then division must be the inverse of multiplication. That isn't what he said, but it may have been what he meant to say. At any rate, the rest of the video is quite clear why x/0 can't be infinity, and I'm no mathematician so that's all I can say about this. Maybe you should watch it again.
I really don't need to, I've gone over all the subjects he discussed in my calculus classes. I know exactly what he's talking about, I just don't agree with it.
You're aware that this is a misconception, correct? This was made because of the last two symbols. The proper numbers for the flights are as follows.
American Airlines Flight 11 - North Tower
United Airlines Flight 175 - South tower
American Airlines Flight 77 - Pentagon
United Airlines Flight 93 - Aimed at DC, but was taken back by passengers, and crashed into a field.
