Why 1729 is a special number

Syracuse, the Greek island of Sicily was his birthplace. Arithmetic: It is the oldest and the most elementary among other branches of mathematics. It deals with numbers and the basic operations- addition, subtraction, multiplication, and division, between them. Algebra: It is a kind of arithmetic where we use unknown quantities along with numbers.

Perfect number, a positive integer that is equal to the sum of its proper divisors. Other perfect numbers are 28, , and 8, So, the prime factors of are 7, 13 and We observe that they are already arranged in ascending order. It is also a sphenic number. Investigating pairs of distinct integer-valued quadratic forms that represent every integer the same number of times, Schiemann found that such quadratic forms must be in four or more variables, and the least possible discriminant of a four-variable pair is Guy Because in base 10 the number is divisible by the sum of its digits, it is a Harshad number.

In base 12, is written as , so its reciprocal has only period 6 in that base. The integer pairs a,b are 25,23 , 32,15 , 37,8 and 40,3. List of numbers — Integers. Labels Mathematics. Labels: Mathematics. Ehtisham 21 September at December 05, About the Book: R. This book is the one of the best books in Mathematics for beginners. Although all the topics are covered very well but the topics of Algebra have an edge over others. Permutations and Combinations, Probability, Quadratic equations and Determinants are worth mentioning.

It's a one stop book for beginners. Born in Tamil Nadu's Erode on December 22, , the self-taught mathematical prodigy Srinivasa Ramanujan made extraordinary contributions to mathematical analysis, number theory, infinite series and continued fractions. He was fascinated by numbers and made some remarkable contributions to the partitio numerorum branch of mathematics that deals with the study of partitions of numbers. The mathematical genius compiled approximately results independently before his untimely demise in Kumbhakonam at the age of 32 due to tuberculosis.

His most popular discovery, however, remains the Hardy-Ramanujan number to this date. Hardy said that he came in a taxi having the number '', which the British mathematician described "as rather a dull one". Hardy when he visited Indian mathematician Srinivasa Ramanujan in hospital…. A magic square is an NxN matrix in which every row, column, and diagonal add up to the same number. Srinivasa Ramanujan was an Indian mathematician.
