«والستة ضعف الثلاثة»
And six is twice three.

“Six” and “twice three” have different conceptual expressions but refer to the same numerical quantity. The truth is not confined to any one actual occasion of counting.

Six books can be twice a set of three books, but the relation did not come into being because those particular books were counted. The basis of the proposition is the numerical relation itself, which makes this a real proposition in the textbook's sense.
