In his 1820 book The Philosophy of Arithmetic, [7] mathematician John Leslie published a multiplication table up to 99 × 99, which allows numbers to be multiplied in pairs of digits at a time. Leslie also recommended that young pupils memorize the multiplication table up to 50 × 50.
Tes parents ont un iPhone? Alors tu vas pouvoir apprendre les tables de multiplication sur mobile. Avec ces flashcards en ligne c'est plus facile d'apprendre les tables de multiplication. Pour tous ceux qui ont un Iphone, un Ipad... un smartphone, bref un téléphone portable. Cycles of the unit digit of multiples of integers ending in 1, 3, 7 and 9 (upper row), and 2, 4, 6 and 8 (lower row) on a telephone keypadAfter coming to the top of this column, start with the bottom of the next column, and travel in the same direction. The number is 8. So think of the next number after 21 that ends with 8, which is 28. Nous te conseillons de t'exercer tous les jours pendant 10 minutes pour un résultat optimal.

A modern representation of the Warring States decimal multiplication table used to calculate 12 × 34.5 Standards-based mathematics reform in the US [ edit ] The multiplication table is sometimes attributed to the ancient Greek mathematician Pythagoras (570–495BC). It is also called the Table of Pythagoras in many languages (for example French, Italian and Russian), sometimes in English. [4] The Greco-Roman mathematician Nichomachus (60–120AD), a follower of Neopythagoreanism, included a multiplication table in his Introduction to Arithmetic, whereas the oldest surviving Greek multiplication table is on a wax tablet dated to the 1st century AD and currently housed in the British Museum.

Smith (1958), History of Mathematics, Volume I: General Survey of the History of Elementary Mathematics. New York: Dover Publications (a reprint of the 1951 publication), ISBN 0-486-20429-4, pp. 58, 129. Mokkan discovered at Heijō Palace suggest that the multiplication table may have been introduced to Japan through Chinese mathematical treatises such as the Sunzi Suanjing, because their expression of the multiplication table share the character 如 in products less than ten. [8] Chinese and Japanese share a similar system of eighty-one short, easily memorable sentences taught to students to help them learn the multiplication table up to 9 × 9. In current usage, the sentences that express products less than ten include an additional particle in both languages. In the case of modern Chinese, this is 得 ( dé); and in Japanese, this is が ( ga). This is useful for those who practice calculation with a suanpan or a soroban, because the sentences remind them to shift one column to the right when inputting a product that does not begin with a tens digit. In particular, the Japanese multiplication table uses non-standard pronunciations for numbers in some specific instances (such as the replacement of san roku with saburoku).

In mathematics, a multiplication table (sometimes, less formally, a times table) is a mathematical table used to define a multiplication operation for an algebraic system.Then use the Math Trainer - Multiplication to train your memory, it is specially designed to help you memorize the tables.
The decimal multiplication table was traditionally taught as an essential part of elementary arithmetic around the world, as it lays the foundation for arithmetic operations with base-ten numbers. Many educators believe it is necessary to memorize the table up to 9 × 9. [1] History [ edit ] Pre-modern times [ edit ] The Tsinghua Bamboo Slips, Chinese Warring States era decimal multiplication table of 305BC The 10 times table is one of the easiest to learn. For a start, numbers in the 10 times table always end in a 0. And then the 5 and the 2 multiplication tables are also one of the easiest. Tables can also define binary operations on groups, fields, rings, and other algebraic systems. In such contexts they are called Cayley tables. Here are the addition and multiplication tables for the finite field Z 5: In 493AD, Victorius of Aquitaine wrote a 98-column multiplication table which gave (in Roman numerals) the product of every number from 2 to 50 times and the rows were "a list of numbers starting with one thousand, descending by hundreds to one hundred, then descending by tens to ten, then by ones to one, and then the fractions down to 1/144." [6] Modern times [ edit ] C’est la base des problèmes que tu devras résoudre en CE2, CM1 et CM2, c’est donc important de bien connaître tes tables de multiplication.The illustration below shows a table up to 12 × 12, which is a size commonly used nowadays in English-world schools. Trivett, John (1980), "The Multiplication Table: To Be Memorized or Mastered!", For the Learning of Mathematics, 1 (1): 21–25, JSTOR 40247697 . This form of writing the multiplication table in columns with complete number sentences is still used in some countries, such as Bosnia and Herzegovina, [ citation needed] instead of the modern grids above. The next number in the direction of the arrow is 1. So think of the next number after 14 that ends with 1, which is 21.
