Definition: In mathematics, a joint (or cross) product is the result of multiplying two or more variables together. It represents the action of two or more quantities on each other. For example: - The product of 2 and 3 is 6. - The product of 4 and 5 is 20. The terms "joint" and "cross" are often used in algebra to denote this kind of multiplication, as they stand for the action of two or more quantities on each other
