It is so too equal! Multiplication is commutative.

Unless A and B are matrices. Matrix multiplication is NOT commutative. Whether or not AxB = BxA depends upon the definition of the binary operator x [multiply] in the domain over which it is defined.

I don't think this means multiplication. I think it is talking about the Cartesian cross product. Either way, if A and B are matrices, then, no, it is not equal because matrix multiplication is NOT commutative.

axb equals bxa because lets say that a is 7 and b is 6.7x6 is 42 and 6x7 is 42

What is the commutitive law of multiplication?

The Commutative law states that, if AxB=y, and BxA=y, then AxB=BxA Or we can just say it says AB=BA where A and B are any numbers, real or complex.


What are all of the multiplicative identities?

What is commutative in mathmatics?

The term related to Commutative Laws simply states that you can swap numbers in an equation and still get the same answer. For example a+b=b+a or axb=bxa.


Is the multiplicand on the top or bottom of a question?

If your math teacher is insisting that you learn terms like "multiplicand" and thinks it makes a difference whether you multiply AxB or BxA, then go to the school office and see if you can get transferred to a different class. Multiplication is commutative.

If the commutative law not hold in cross product then prove it?

Actually The cross product of two vector is a VECTOR product. The direction of a vector product is found by the right hand rule. Consider two vectorsA and B,AxB= CWhere C is the Cross product of A and B, and by right hand rule its direction is opposite to that of BxA that isBxA=-C

If AxB is zero and A and B are non zero then prove that A is parallel to B?

If A and B are vectors then AxB=ABsin(AB). If A and B are not zero then AxB is zero if and only if sin(AB)=0 meaning the angle between A and B is a multiple of 180 degrees, in other words parallel.


In a gm ABCD the bisector of angle A also bisect BC at X. Prove tht AD2 AB?

AX bisects angle DAB so angles DAX and XAB are equal. .. .. .. .. .. .. .. .. (i)DA is parallel to CB and AX is an intercept.So angle DAX and AXB are alternate angles and therefore angles DAX and AXB are equal.Therefore, by (i) angles XAB and AXB are equal.Thus triangle BAX is isoscelestherefore AB = BX.BX = 1/2*BC = 1/2*AD (since ABCD is a parallelogram).Therefore AB = BX = AD/2.


What is the answer for a x b x c?

if x = multiplication. its as written, which would be abc ex. 3x4x5 = (3)(4)(5) = 60 if x= cross production, then you cross axb first, then bross (axb) x c where (axb) is wut u got by crossing axb. This is if u have no brackets. its just axbxc
