==Examples==

* In order to be conformable to addition, matrices need to have the same dimensiondimensions. Thus ''A'', ''B'' and ''C'' all must have dimensions ''m'' × ''n'' in the equation

::<math>A + B = C</math>

Line 12:

::<math>AB = C.</math>

:If ''A'' has dimensiondimensions ''m'' &times; ''n'', then ''B'' has to have dimensiondimensions ''n'' &times; ''p'' for some ''p'', so that ''C'' will have dimensiondimensions ''m'' &times; ''p''.
