Linear algebra quick silly question

  1. Jan 15, 2014 #1
    so i just wanted to get this confirmed: the only two defined algebraic operations for matrices are addition and multiplication right?

    Perhaps you mean "arithmetic" rather than "algebraic" ?

    How about subtraction?

    i was including subtraction when i mentioned addition. and yes, "arithmetic" operations.

    so that's all right? addition/subtraction and multiplication?

    In particular, division is not defined for matrices .

    do transposes, traces, etc all count as algebraic operations?

    I don't know about the "algebraic" part, but they are certainly operations that are defined on matrices.
