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: 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 keypad 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). When you finished the 5 steps you can play the memory game or exercise with the worksheet. Other way to train more are with the tempo test, the 1 minute test or to play the times tables games. 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.

There is a pattern in the multiplication table that can help people to memorize the table more easily. It uses the figures below: 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.

Step 4: Multiple choice questions will help you to improve by looking at the questions in a different way. IBM 1620, an early computer that used tables stored in memory to perform addition and multiplication 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. After 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. 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.
