How To Multiply Matrices?

<p>I totally forgot how to multiply matrices, and it’s part of my homework tonight. I know that homework questions are not allowed so I am not answering for the answer to the problem, I just need a quick reminder on how to multiply the matrices on the TI-83 calculator. I’ve got them plugged in and everything, I just can’t figure out how to multiply the two.</p>

<p>Thank you!</p>

<p>I have a ti-84 but I assume its the same. if you have them plugged in already when you go to the matrix screen it should say names at the top and have a list “1 [A] 2 **…” and you just pick the first one you want…then multiplication sign (not even necessary)…then the other one…then press enter.</p>
