    first you want to ake sure it'spossible by seeing that n=m if they do it's possible to multiply in this case you have 2 rows and 2 columns in the other one so it's possible

    I know that the Dimensions have to be same, but i get stuck on which number should multiply which other number.

    if you have a graphing calculator there is a matrix button. 2nd-matrix.. and you can edit your matrix in and then multiply them together. you can probably find info on the net about how to do this as i don't have my graphing calculator with me and it's hard to explain

    however if you're in an actual classroom i do believe you should know how to do it by hand as your teacher is probably trying to make sure you understand the concept of doing by hand. when you get into higher classes when you're doing huge matrices, they just tell you to use calculators
