You can put this solution on YOUR website!
You can list them in order, like,
\n" ); document.write( "[A] is a 2x2 matrix [A]=(1 2 3 4) for [A]= $\"%28matrix%282%2C2%2C1%2C2%2C3%2C4%29%29\"$
\n" ); document.write( "[B] is a 3x3 matrix [B]=(9 8 7 6 5 4 3 2 1) for [B]= $\"%28matrix%283%2C3%2C9%2C8%2C7%2C6%2C5%2C4%2C3%2C2%2C1%29%29\"$
\n" ); document.write( "[C] is a 3x1 matrix [C]=(x y z) for [C]= $\"%28matrix%283%2C1%2Cx%2Cy%2Cz%29%29\"$
\n" ); document.write( "Then solve,
\n" ); document.write( "4[B][C]-12[C] \n" ); document.write( "

\n" );
