2. Multiplication table - Wikipedia

   en.wikipedia.org/wiki/Multiplication_table

   Multiplication table from 1 to 10 drawn to scale with the upper-right half labeled with prime factorisations. 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.

   Multiplication can also be thought of as scaling. Here, 2 is being multiplied by 3 using scaling, giving 6 as a result. Animation for the multiplication 2 × 3 = 6 4 × 5 = 20. The large rectangle is made up of 20 squares, each 1 unit by 1 unit. Area of a cloth 4.5m × 2.5m = 11.25m 2; 4 ⁠ 1 / 2 ⁠ × 2 ⁠ 1 / 2 ⁠ = 11 ⁠ 1 / 4 ⁠

4. Table of prime factors - Wikipedia

   en.wikipedia.org/wiki/Table_of_prime_factors

   A perfect power has a common divisor m > 1 for all multiplicities (it is of the form a m for some a > 1 and m > 1). The first: 4, 8, 9, 16, 25, 27, 32, 36, 49, 64, 81, 100 (sequence A001597 in the OEIS). 1 is sometimes included. A powerful number (also called squareful) has multiplicity above 1 for all prime

5. Multiplication sign - Wikipedia

   en.wikipedia.org/wiki/Multiplication_sign

   The multiplication sign (×), also known as the times sign or the dimension sign, is a mathematical symbol used to denote the operation of multiplication, which results in a product. [ 1 ] The symbol is also used in botany , in botanical hybrid names .

6. Seven-dimensional cross product - Wikipedia

   en.wikipedia.org/wiki/Seven-dimensional_cross...

   The product can be given by a multiplication table, such as the one here. This table, due to Cayley, [3] [4] gives the product of orthonormal basis vectors e i and e j for each i, j from 1 to 7.

7. Cayley table - Wikipedia

   en.wikipedia.org/wiki/Cayley_table

   The group {1, −1} above and the cyclic group of order 3 under ordinary multiplication are both examples of abelian groups, and inspection of the symmetry of their Cayley tables verifies this. In contrast, the smallest non-abelian group, the dihedral group of order 6, does not have a symmetric Cayley table.
