You can indicate the multiplication with a multiplication sign. If your matrices are "A" and "B", the product is: A x B In other words, you are indicating the product, but not actually carrying out any multiplication. Anybody who understands about matrices should know what this refers to.
two times two
The commutative property of an operation ~, defined on a set S requires that: for any two elements of S, say x and y, x ~ y = y ~ x Familiar examples are ~ = addition or multiplication and S is a subset of numbers. But note that multiplication is not commutative over matrices.
2 x 6 = 12 2 x 2 x 3 = 12
2 times 2 equals 4 * * * * * Given the limitations of this browser, this may not work! Matrix A = (a b) (c d) Matrix B = (w x) (y z) Then AB = (aw+by ax+bz) (bw+dy bx+dz)
