It contains seven-figure logarithms of numbers from I to ,, with characteristics unseparated from the mantissae, and was formed from Vlacq's table () by leaving out the last three figures. All the figures of the number are given at the head of the columns, except the last two, which run down the extreme columns-1 to 50 on the left. His table gives the logarithms of all numbers up to , and of primes (and also of a great many composite numbers) from to 10,, to 48 decimal places. The table appeared in Schulze’s Neue und erweiterte Sammlung logarithmischer Tafeln (), and was reprinted in Vega’s Thesaurus (), already referred to.

8. In the case of any trajectory whatever, the half number of letters in the intercalation is termed the "index," viz. this is either an integer or an integer + 1. But in the case of a circuit the index is an even integer, and the half-index is therefore an integer. The index may of course be = 0. 9.

The product of two numbers is equal to the difference of one-fourth the squares of their sum and their difference: t (a -f b)2 — J (a —b)2. This fact has been used 70 to reduce multiplication to addition with the aid of tables of quarter squares. The method is very old.

The history of logarithms is the story of a correspondence (in modern terms, a group isomorphism) between multiplication on the positive real numbers and addition on the real number line that was formalized in seventeenth century Europe and was widely used to simplify calculation until the advent of the digital computer.

Thus with a table of quarter-squares we can multiply together any two numbers by subtracting the quarter-square of their difference from the quarter-square of their sum. The largest table of quarter-squares is Laundy, Table of Quarter-Squares of all Numbers up to(London, ).

History of logarithms explained. The history of logarithms is the story of a correspondence (in modern terms, a group isomorphism) between multiplication on the positive real numbers and addition on the real number line that was formalized in seventeenth century Europe and was widely used to simplify calculation until the advent of the digital computer.

A multiplication algorithm is an algorithm (or method) to multiply two numbers. Depending on the size of the numbers, different algorithms are in use. Efficient multiplication algorithms have existed since the advent of the decimal system.His table gives the logarithms of all numbers up toand of primes (and also of a great many composite numbers) from to 10, to 48 decimal places.

The table appeared in Schulze's Neue and erweiterte Sammlung logarithmischer Tafeln (), and was reprinted in Vega's Thesaurus (), already referred to.If, for example, you wanted to multiply 9 by 3, you observe that the sum and difference are 12 and 6 respectively.

Looking both those values up on the table yields 36 and 9, the difference of which is 27, which is the product of 9 and 3.
