Commutativity in multiplication
WebIn Part I we have already discussed the commutativity of addition and multiplication of integers. Commutativity of addition meant that, for example, 2+7= 9 2 + 7 = 9 and also 7+2 = 9. 7 + 2 = 9. Also recall that this property does not hold for subtraction, as is proved by the counterexample 2−7 = −5 2 − 7 = − 5 but 7−2 = 5. 7 − 2 = 5. WebThe commutative property of multiplication says that the order in which we multiply two numbers does not change the final product. The image given below represents the commutative property of the multiplication of two numbers.. If 4 and 6 are the numbers, then 4 × 6 = 24, and 6 × 4 is also equal to 24.

To show matrix multiplication is not commutative we can consider an example. Take A = [ 1 1 0 0] B = [ 1 0 0 0] Then A B = [ 1 1 0 0] [ 1 0 0 0] = [ 1 0 0 0] and B A = [ 1 0 0 0] [ 1 1 0 0] = [ 1 1 0 0]
WebThe commutative property is a math rule that says that the order in which we multiply numbers does not change the product. Example: \blueD8 \times \purpleD2 = \pink {16} 8×2 = 16 \quad \purpleD2 \times \blueD8 = \pink {16} 2×8 = 16 So, \blueD8 \times \purpleD2 = \purpleD2 \times \blueD8 8×2 = 2×8.
