Mind Your Decisions is a compilation of 5 books: (1) The Joy of Game Theory: An Introduction to Strategic Thinking
It should therefore be no surprise if the raison d’etre behind the US approach is less than widely understood outside the US. Other people thought about the puzzle in terms of doing the multiplication and then taking the sum of the digits in the answer. In other words, this is finding the “sum of the digits in the product.” Mind Your Puzzles is a collection of the three “Math Puzzles” books, volumes 1, 2, and 3. The puzzles topics include the mathematical subjects including geometry, probability, logic, and game theory.Most people believe the correct answer is 36. The method to obtain the answer is to take the product of the sum of digits in each number being multiplied. Arguably there are many answers, as there are many patterns that fit the given information. However, there are 2 main answers that are most popular. I will go over what many people believe to be the correct answer, and I will explain how the 2 main approaches are flavors of the same idea. US Standard Fan-Fold (aka green bar): 14-7/8″ by 11″– These are/were for the wide pin-feed (teletype / industrial / factory) printers. In the video, I show the same thing visually using diagrams from the “multiply by lines” method. The answer in each case is the number of intersections of the lines or “dots” in the figure, and 33 × 33 has 36 dots. The first multiple they all share is 12, so this is the least common multiple. To complete an addition (or subtraction) problem, multiply the numerators and denominators of each fraction in the problem by whatever value will make the denominators 12, then add the numerators. EX:
Again, the sum of the digits is the sum of the coefficients of the terms attached to powers of 10. The sum is 4 + 8 + 4 = 16. People often ask how I make the videos. Like many YouTubers I use popular software to prepare my videos. You can search for animation software tutorials on YouTube to learn how to make videos. Be prepared--animation is time consuming and software can be expensive!

This list of the common American and European paper sizes includes the ISO standards, which are used globally. All dimensions are specified in inches, millimeters as well as PostScript points (1/72 inch, always rounded off). The overview covers:
The “sum of the digits of the product” gives 18, while the “product of the sum of the digits” gives 36.

The US even insists on a different system of maritime navigation marks whilst everyone else not dominated by big brother uses a different internationally agreed approach.
