Here we prove the theorem about linear transformations from Rn to Rm. Theorem. A function f from Rn to Rm is a linear transformation if and only if it satisfies the following two properties: For every two vectors A and B in Rn. f(A+B)=f(A)+f(B); For every vector A in Rn and every number k. f(kA)=kf(A).

It was popularized in the Amiga computer operating system Amiga OS and later in IBMâs OS/2 but it existed before those on various IBM operating systems for mainframes and minicomputers.
