Jim and his wife, Pam, went to a Valentine’s Day party where four other married couples were present. Every person shook hands with everyone he or she did not know. When they sat down for dinner, Jim asked everyone, including Pam, how many hands they shook. To his surprise, Jim receivednine different answers. How many hands did Pam shake?

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b
