When finding the product,
\n" ); document.write( "-2 0 1
\n" ); document.write( "4 3 2
\n" ); document.write( "-1 5 0
\n" ); document.write( "and
\n" ); document.write( "-1 4 -2
\n" ); document.write( "0 -1 3
\n" ); document.write( "-2 0 -5
\n" ); document.write( "how many pairs of numbers must be multiplied together?
\n" ); document.write( "Each row has to multiply each column (9 actions)and each
\n" ); document.write( "multiplication involves 3 multiplied pairs
\n" ); document.write( "So there are 9*3 multiplied pairs = 27
\n" ); document.write( "-------------------------\r
\n" ); document.write( "\n" ); document.write( "1. What is a square matrix? : one that has an equal number of rows and columns.
\n" ); document.write( "-------------------------
\n" ); document.write( "2. What is meant when a matrix is said to have dimensions \"b\" by \"a\"?
\n" ); document.write( "It has \"b rows and \"a\" columns.
\n" ); document.write( "---------------------------
\n" ); document.write( "3. Under what conditions can two matrices be added?
\n" ); document.write( "If they have the same dimensions: same number of rows and same number of columns.
\n" ); document.write( "---------------------------
\n" ); document.write( "4. What conditions are necessary in order to be able to multiply two matrices?
\n" ); document.write( "The number of columns of the left matrix must equal the number of rows of the
\n" ); document.write( "right matrix.
\n" ); document.write( "------------------------------
