That is side effects.

That is bit-twiddling, not matrix multiplication.

It is very much the same vein.

Hardly.

Boolean or is a binary operation that is commutative in mathematical terms. So is addition. The point is that any operation in computer science is not commutative.

The idea that pure mathematics does not match computational reality is not limited to this point of commutativity. Note, for example, that making a Square class extend a Rectangle (since a Square is-a Rectangle) does not actually work since it would fail to match the Rectangle's contract.
