Probably you mean I − 134I. If I denotes the identity matrix (or any symbol for a matrix/vector that you scale), scalar multiplication distributes, so
I − 134I = (1 − 134)I = −133 I.
Example: for a 2×2 identity I = [[1,0],[0,1]],
I − 134I = [[1−134,0],[0,1−134]] = [[−133,0],[0,−133]] = −133 I.
If I was the imaginary unit i instead, i − 134i = −133i — the same algebraic idea.
I − 134I = (1 − 134)I = −133 I.
