"WebAug 9, 2012 · By definition, you can only add/subtract matrices of the same dimension. While Daryl is right, some programming languages may allow you to do something like 3 - [2, 1]. They do this by converting scalar to appropriate size matrix. So 3 - [2, 1] is same converted to [3, 3] - [2, 1] which gives [1, 2] as the final result (as suggested by Fabian).

Matrix addition & subtraction (article) Khan Academy

WebSubtraction as the addition of the opposite. Another way scalar multiplication relates to addition and subtraction is by thinking about \bold A-\bold B A −B as \bold A+ (-\bold B) A+(−B), which is in turn the same as \bold A+ (-1)\cdot\bold B A +(−1)⋅B. This is similar to how we can think about subtraction of two real numbers!
