Show property :

a . `b times c = c times b`
b.   ` a times c = c times a `

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

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

Evaluate : a times a times a times b times b times c times c times c times c

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

Show : A times ( B - C ) = ( A times B ) - ( A times C )

a times a times a times b times b times c times c times c times c times c

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

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

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

Evaluate : a times b times a times b times c times c times c
