Example 12 Find AB, if A = [■8(6&9@2&3)] and B = [■8(2&6&0@7&9&8)] A = [■8(6&9@2&3)] and B = [■8(2&6&0@7&9&8)] AB = [■8(6&9@2&3)]_(2×2) 〖" " [■8(2&6&0@7&9&8)]〗_(2×3) = [■8(12+63&36+81&0+72@4+21&12+27&0+24)] = [■8(𝟕𝟓&𝟏𝟏𝟕&𝟕𝟐@𝟐𝟓&𝟑𝟗&𝟐𝟒)] = [█(█( @ ) @ @ )]_(𝟐 × 𝟑) On multiplying matrices with order 2 × 2 & 2 × 3 we get order 2 × 3
