4. To carry out the matrix multiplication, first
   type [A][B]in cell A18, as shown. Then
   pick cells B17 through D19.


5. In the Formula bar, type MMULT
   (B3:D5,G3:I5), and, while holding down
   theCtrland theShiftkeys, press theEnter
   key. Similarly, you can perform the matrix
   operation[A]{C}. First you pick cells B21
   through B23, in the Formula bar, type
   MMULT(B3:D5,L3:L5), and, while
   holding down the Ctrland the Shiftkeys,
   press the Enterkey. This sequence of oper-
   ations will create the result shown in the
   accompanying figure.
