The expression "A × B" represents the mathematical operation of multiplication, where A and B are numbers or variables. In this operation, A is multiplied by B to produce a product, which is the result of the multiplication. For example, if A is 3 and B is 4, then 3 × 4 equals 12. Multiplication can also be visualized as repeated addition. For instance, multiplying 3 by 4 means adding 3 together four times: 3 + 3 + 3 + 3 = 12. This concept is fundamental in mathematics and is used in various applications, including algebra, geometry, and statistics.
