In its Fifth Assessment Report, the Intergovernmental Panel on Climate Change, a group of 1,300 independent scientific experts from countries all over the world under the auspices of the United Nations, concluded there's a more than 95 percent probability that human activities over the past 50 years have warmed our planet.
Scalar multiplication of two vectors (to give the so-called dot product) is commutative (i.e., aÂ·b = bÂ·a), but vector multiplication (to give the cross product) is not (i.e., a Ã b = âb Ã a). The commutative law does not necessarily hold for multiplication of conditionally convergent series.
Thus commutative principle for multiplication shows that the order does not matter and 3 X 4 = 4 x 3 or the general form: (A)(B)$\equiv$(B)(A). * * * * * * * * * * | * * * * * * * * * * * * | * * * * * * * * * * * * | * *.
