    • @kroxmetic5126

      That's a great observation! I think Arthur Benjamin takes more time saying the answer than he does solving the problem for a few reasons.
      First, he wants to make sure that he explains the answer clearly and concisely. He doesn't want to just give the answer and leave the audience confused. He wants to help them understand how he got to the answer and why the answer is correct.
      Second, Benjamin uses his time to entertain the audience. He is a skilled storyteller and communicator, and he enjoys telling stories and jokes to illustrate his points. He also likes to interact with the audience and ask them questions.
      Third, Benjamin takes his time to inspire the audience. He wants to show them that mathematics is a beautiful and powerful subject. He wants them to see that mathematics can be used to solve real-world problems and to make the world a better place.
      Overall, I think Arthur Benjamin takes more time saying the answer than he does solving the problem because he wants to explain the answer clearly, entertain the audience, and inspire them. He is a gifted teacher and communicator, and he uses his time to share his love of mathematics with the world.
      I find his approach to teaching mathematics very refreshing. He is not just interested in teaching students how to solve problems. He also wants to teach them how to think critically and to appreciate the beauty of mathematics.
      I am grateful for Arthur Benjamin's contributions to the field of mathematics education. He is an inspiration to me and to many other students and teachers.

      ​@damn8633 Nah
      The impressive part isn't the calculation, honestly
      It's being able to accurately keep track of how many digits the solution has and properly saying the final answer...
      I was messing around with speed mental mathematic techniques and they pretty much all work the same way as regular multiplication on paper.
      As in, when you do the calculation in your head you won't arrive at: "three million two hundred twenty seven thousand six hundred and seventy three"...
      (3,227,673 for looks)
      You'd solve it and you'd get something like: "three, seven, six, seven, two, two, three"
      ...which doesn't matter for calculating, but being able to count all the digits, reverse the order, and then correctly label the number in real-time is pretty damn impressive, honestly.
      It's called the Trachtenberg method

      Each rocket consisted of 26 math tests, one for each letter, and each test would get slightly harder and you would have to try and finish the problems within the given time to move onto the next letter. After Z, you move to the next rocket.

      There are easy tricks to calculate them, for 2 digits for example: www.quickanddirtytips.com/education/math/how-to-square-two-digit-numbers-in-your-head?page=all
      for squaring with 3 digit numbers:
      math.stackexchange.com/questions/157206/square-three-digit-numbers-the-efficient-way (I like the second answer)
      I'm pretty sure there will be tricks for more digit squaring aswel

      Look for the biggest number he answered with, and call it N (for a way to get the range). Then count the number of questions, which we can say is Q. Then let P (probability of guessing the numbers) be (1/N)^Q. I know it changes if you stop counting the numbers that he already answered or that he asked for an X digit number and so on, but you would be right in saying that the answer is 0 whatever the case might be.

      yeah he's more entertaining than teaching. What puzzles me is how he used words as part of his math... if I try associate numbers with words I just make even bigger mess ; it doesn't help me to remember more at all; just confuses me.

      This isn't him flexing. When you were in school/college/university and they are going to teach a subject, I'm sure 90% of the time the very first thing they do or ask is "What is [this subject]?" Arthur did that when he introduced Mathemagics. He tells you what it is, then proceeds to show that it works and tries to give a glimpse into how it works in his head. If you want to learn how to do it, I'm sure it's another class or Ted talk you'll have to take.

    For the numbers to words code the numbers 0-9 represents different sounds:
    1 - t,d (imagine ones making a T)
    2 - n (two downward lines)
    3 - m (three downward lines)
    4 - r (fouR)
    5 - L (Roman numerals L is 50)
    6 - sh, ch or j or soft g
    7 - k or ck (imagine K as two 7's)
    8 - f or v (imagine fancy f in 8)
    9 - b or p (p 9 are similar)
    0- z or s
    Vowels you can make up as you please to form the sounds into words.
    Light tomorrow = 51 134
    We can ignore silent letters it's all about sounds. This method helps you convert numbers into letters and allow you to memorize them
