Find the value of
`( a - b ) times ( a + b ) + ( b -c ) times ( b + c ) + ( c + a ) times ( c - a ) =`

A)   -1  
B)   0  
C)   1  

Evaluate : ( 1/b + 1 ) times ( 1/c + 1 ) times ( 1/b ) times ( 1/c )

Evaluate : [ ( a times b ) times ( b times c ) ( b times c ) times ( c times a ) ( c times a ) times ( a times b ) ]

Explain : a times ( b + c ) = ( a times b ) + ( a times c )

The value of x^(a-b)times x^(b-c)times x^(c-a) is a. 1 b. 2 c. x d. 0

Evaluate : ( b times c ) times ( c times a ) =

Show : ( a/b times c/d ) = ( a times c )/ ( b times d )

Evaluate : ( b times c ) times ( c times a )

If a + b + c = 0 , then find the value of ( ( a + b ) / c + ( b + c )/a + ( c + a ) / b ) times ( a /( b + c ) + b /( c + a ) + c /( a + b ) ) is :

The value of [a times b, b times c, c times a] is
