This is a facsimile of the pages from the Katsuyo Sampo of en:Seki Kowa that tabulate the binomial coefficients and the Bernoulli numbers. Seki died in 1708, and the work was published in 1712, so it is in the public domain.
The bottommost row tabulates the Bernoulli numbers. The rightmost value is a special case, 全 ("everything"). Each of the other entries is either 空 (zero, literally, "empty") or a fraction n/d in the form d分之n. (See en:Chinese_numerals#Fractional_values for an elaboration of this notation.) There is a small double mark 二 in the margin before the denominatord and a small single mark 一 in the margin after the numerator n. So for example the fraction in the third column from the right (representing ) is written as 六分之一, which means 1/6; the fraction in the seventh column () is written 四十二分之一, which means 1/42. The sign is given by the characters under the marginal 一 mark, with 爲加 ("add") indicating positive values, and 爲減 ("reduce") indicating negative values.
The complete reading of the bottom row, right to left, is: "everything", 1/2, 1/6, 0, -1/30, 0, 1/42, 0, -1/30, 0, 5/66, 0.
This work is in the public domain in its country of origin and other countries and areas where the copyright term is the author's life plus 70 years or fewer.
You must also include a United States public domain tag to indicate why this work is in the public domain in the United States.
Note that a few countries have copyright terms longer than 70 years: Mexico has 100 years, Jamaica has 95 years, Colombia has 80 years, and Guatemala and Samoa have 75 years. This image may not be in the public domain in these countries, which moreover do not implement the rule of the shorter term. Honduras has a general copyright term of 75 years, but it does implement the rule of the shorter term. Copyright may extend on works created by French who died for France in World War II (more information), Russians who served in the Eastern Front of World War II (known as the Great Patriotic War in Russia) and posthumously rehabilitated victims of Soviet repressions (more information).
