You can use 42 multiplication table to practice your multiplication skills with our online examples or print out our free Multiplication Worksheets to practice on your own. 42 Times Tables Chart A question that naturally follows is: Is there at least one solution for every nonprohibited value? Computers at Work Since the first such school was created in France in 2013 there has been a proliferation of private computer-training institutions in the “42 Network,” whose name is a clear allusion to Adams’s novels. Today the founding company counts more than 15 campuses in its global network. The number 42 also appears in different forms in the film Spider-Man: Into the Spider-Verse. Many other references and allusions to it can be found, for example, in the Wikipedia entry for “42 (number).” The problem is stated as follows: What integers n can be written as the sum of three whole-number cubes ( n = a 3 + b 3 + c 3)? And for such integers, how do you find a, b and c ? As a practical matter, the difficulty in making this calculation is that for a given n, the space of the triplets to be considered involves negative integers. This triplet space is therefore infinite, unlike the computation for the sum of squares. For that particular problem, any solution has an absolute value lower than the square root of a given n. Moreover for the sum of squares, we know perfectly well what is possible and impossible. Multiplication Table is an useful table to remember to help you learn multiplication by 42. You should also practice the examples given because the best way to learn is by doing, not memorizing. Online Practice

The number 42 also turns up in a whole string of curious coincidences whose significance is probably not worth the effort to figure out. For example: The answer came in a 2020 preprint, the result of a huge computational effort coordinated by Booker and Andrew Sutherland of the Massachusetts Institute of Technology. Computers participating in the Charity Engine network of personal computers, calculating for the equivalent of more than one million hours, showed: This sum of three cubes puzzle, first set in 1954 at the University of Cambridge and known as the Diophantine Equation x 3+y 3+z 3=k, challenged mathematicians to find solutions for numbers 1-100. With smaller numbers, this type of equation is easier to solve: for example, 29 could be written as 3 3 + 1 3 + 1 3, while 32 is unsolvable. All were eventually solved, or proved unsolvable, using various techniques and supercomputers, except for two numbers: 33 and 42. Note that for some integer values of n, the equation n = a 3 + b 3 + c 3 has no solution. Such is the case for all integers n that are expressible as 9 m + 4 or 9 m + 5 for any integer m (e.g., 4, 5, 13, 14, 22, 23). Demonstrating this assertion is straightforward: we use the “modulo 9” (mod 9) calculation, which is equivalent to assuming that 9 = 0 and then manipulating only numbers between 0 and 8 or between −4 and 4. When we do so, we see that: The centimeter (symbol: cm) is a unit of length in the metric system. It is also the base unit in the centimeter-gram-second system of units. The centimeter practical unit of length for many everyday measurements. A centimeter is equal to 0.01 (or 1E-2) meter. Centimeters to inches formula and conversion factor

mod 9); 1 3 = 1 (mod 9); 2 3 = 8 = –1 (mod 9); 3 3 = 27 = 0 (mod 9); 4 3 = 64 = 1 (mod 9); 5 3 = (–4) 3 = –64 = –1 (mod 9); 6 3 = (–3) 3 = 0 (mod 9); 7 3 = (–2) 3 = 1 (mod 9); 8 3 = (–1) 3 = –1 (mod 9) Apart from allusions to 42 deliberately introduced by computer scientists for fun and the inevitable encounters with it that crop up when you poke around a bit in history or the world, you might still wonder whether there is anything special about the number from a strictly mathematical point of view. Mathematically Unique?

The author’s choice of the number 42 has become a fixture of geek culture. It’s at the origin of a multitude of jokes and winks exchanged between initiates. If, for example, you ask your search engine variations of the question “What is the answer to everything?” it will most likely answer “42.” Try it in French or German. You’ll often get the same answer whether you use Google, Qwant, Wolfram Alpha (which specializes in calculating mathematical problems) or the chat bot Web app Cleverbot.Booker and Sutherland discussed the algorithmic strategy to be used in the search for a solution to 42. As Booker found with his solution to 33, they knew they didn’t have to resort to trying all of the possibilities for x, y, and z.

In a 2016 preprint paper, Sander Huisman, now at the University of Twente in the Netherlands, pressed on and found a solution for 74: The marathon distance of 42.195 kilometers corresponds to the legend of how far the ancient Greek messenger Pheidippides traveled between Marathon and Athens to announce victory over the Persians in 490 B.C. (The fact that the kilometer had not yet been defined at that time only makes the connection all the more astonishing.) All this is amusing, but it would be wrong to say that 42 is really anything special mathematically. The numbers 41 and 43, for example, are also elements of many sequences. You can explore the properties of various numbers on Wikipedia. Like other computational number theorists who work in arithmetic geometry, he was aware of the “sum of three cubes” problem. And the two had worked together before, helping to build the L-functions and Modular Forms Database (LMFDB), an online atlas of mathematical objects related to what is known as the Langlands Program. “I was thrilled when Andy asked me to join him on this project,” says Sutherland.

The factor 2.54 is the result from the division 1 / 0.393701 (centimeter definition). Therefore, another way would be: Sutherland, whose specialty includes massively parallel computations, broke the record in 2017 for the largest Compute Engine cluster, with 580,000 cores on Preemptible Virtual Machines, the largest known high-performance computing cluster to run in the public cloud.

The Gutenberg Bible, the first book printed in Europe, has 42 lines of text per column and is also called the “Forty-Two-Line Bible.” But both are more interested in a simpler but computationally more challenging puzzle: whether there are more answers for the sum of three cubes for 3. An inch (symbol: in) is a unit of length. It is defined as 1⁄12 of a foot, also is 1⁄36 of a yard. Though traditional standards for the exact length of an inch have varied, it is equal to exactly 25.4 mm. The inch is a popularly used customary unit of length in the United States, Canada, and the United Kingdom. Definition of centimeterTo calculate an inch value to the corresponding value in centimeters, just multiply the quantity in inches by 2.54 (the conversion factor). Inches to centimeters formulae When I heard the news, it was definitely a fist-pump moment,” says Sutherland. “With these large-scale computations you pour a lot of time and energy into optimizing the implementation, tweaking the parameters, and then testing and retesting the code over weeks and months, never really knowing if all the effort is going to pay off, so it is extremely satisfying when it does.” The number is the sum of the first three odd powers of two—that is, 2 1 + 2 3 + 2 5 = 42. It is an element in the sequence a( n), which is the sum of n odd powers of 2 for n> 0. The sequence corresponds to entry A020988 in The On-Line Encyclopedia of Integer Sequences (OEIS), created by mathematician Neil Sloane. In base 2, the nth element may be specified by repeating 10 n times (1010 ... 10). The formula for this sequence is a( n) = (2/3)(4 n– 1). As n increases, the density of numbers tends toward zero, which means that the numbers belonging to this list, including 42, are exceptionally rare. In ancient Egyptian mythology, during the judgment of souls, the dead had to declare before 42 judges that they had not committed any of 42 sins.
