Graham was solving a problem in an area of mathematics called Ramsey theory.

Though too large to be computed in full, many of the last digits of Graham's number can be derived through simple algorithms.

However, each additional up-arrow requires repeated application of the previous level of up-arrows. Named after Benjamin Graham, the founder of value investing, the Graham number can be calculated as follows: {\begin{matrix}3^{3^{3}}\end{matrix}}\right\}3},g1=33⋅⋅⋅⋅3}33⋅⋅⋅3}…333}3,where the number of towers is33⋅⋅⋅3}333}3, where the number of 3s in each tower, starting from the leftmost tower, is specified by the value of the next tower to the right. Value investors like Warren Buffett select undervalued stocks trading at less than their intrinsic book value that have long-term potential.

Essentially, this second method of calculation is equivalent to the first, wherein EPS = net income/shares outstanding, and book value is another term for shareholders’ equity. 5138 (

… and where the number of 3s in each tower, starting from the leftmost tower, is specified by the value of the next tower to the right. becomes, solely in terms of repeated "exponentiation towers," 2 At Graham Auto Mall we pride ourselves on being the most reliable and trustworthy Chevy, Cadillac, Ford, Hyundai and … He proved that the answer to his problem was smaller than Graham's number. Colour each of the edges of this graph either red or blue. n (This figure corresponds to 15 times earnings and 11⁄2 times book value. ( ↑↑ H

Except for omitting any leading 0s, the final value assigned to x (as a base-ten numeral) is then composed of the d rightmost decimal digits of 3↑↑n, for all n > d. (If the final value of x has fewer than d digits, then the required number of leading 0s must be added.).

Therefore, the first level of up-arrow notation is just exponentiation, and we can write 3↑43 \uparrow 43↑4 as 34.3^4.34. c 2

However, Graham's number can be explicitly given by computable recursive formulas using Knuth's up-arrow notation or equivalent, as was done by Graham. ⋅

Graham and Rothschild (1971) also provided a lower limit by showing that must be at least With regard to stocks and equity instruments, fundamental analysis is a method of determining value that focuses on key metrics and economic indicators, such as revenues, earnings, where an industry is in its cycle, return on equity (ROE), and profit margins.

Trans. ( Additionally, smaller upper bounds on the Ramsey theory problem from which Graham's number derived have since been proven to be valid.

It is so large that the observable universe is far too small to contain an ordinary digital representation of Graham's number, assuming that each digit occupies one Planck volume which equals to about 4.2217×10−105 m34.2217\times 10^{-105}\text{ m}^{3}4.2217×10−105 m3.

– investopedia The Graham Number Formula Before getting into the meat of the formula, you can use tangible book value to make the number more reflective of tangible assets instead of goodwill and intangibles. In 1971, Graham and Rothschild proved that this problem has a solution N∗,N^*,N∗, giving as a bound 6≤N∗≤N,6 \le N^* \le N,6≤N∗≤N, with NNN being a large but explicitly defined number where the number of arrows in each subsequent layer is specified by the value of the next layer below it; that is, The #1 tool for creating Demonstrations and anything technical.

64 Though too large to be computed in full, the sequence of digits of Graham's number can be computed explicitly through simple algorithms. The length of the cycle and some of the values (in parentheses) are shown in each cell of this table: The particular rightmost d digits that are ultimately shared by all sufficiently tall towers of 3s are in bold text, and can be seen developing as the tower height increases.

Knowledge-based programming for everyone.

This weaker upper bound for the problem, attributed to an unpublished work of Graham, was eventually published and named by Martin Gardner in Scientific American in November 1977.

( ) A simple algorithm[8] for computing these digits may be described as follows: let x = 3, then iterate, d times, the assignment x = 3x mod 10d. A stock has earnings per share of $2.50 and a book value per share of $17.92. 7625597484987 According to the theory, any stock price below the Graham number is considered undervalued and thus worth investing in. [3] The lower bound of 6 was later improved to 11 by Geoffrey Exoo in 2003,[4] and to 13 by Jerome Barkley in 2008.

The term is also sometimes referred to as Benjamin Graham’s number. Note that the result of calculating the third tower is the value of n, the number of towers for g1. ,
