    A= (19 81)
    (2 10)

    B= (9 -6)
    (6 -7)

    The book i have tells me how to add multiply and subtract matrices, i dont understand what evaluate AB means, is it multiply>?

    Kind regards

    "Evaluate AB" means "Multiply A by B".

    Whenever two letters are together like that it always means to multiply. AB = [tex] A \times B [/tex]
