Webbcutting and laying carpet needs to know some basic mathematics—but mathe matics is not the science of room measuring or carpet cutting. In mathematics one talks about angles, lengths, areas, and so on, and one discusses the laws governing them: if this length is smaller than that one, then that angle must be bigger than this one, and so on.

Jevons remarks that these simple propositions have no recognised place in Aristotle's logic, although it is impossible not to use them in scientific reasoning (which Aristotle does in at least one place). WebbTwo compound propositions are called logically equivalent or simply equivalent if they have identical truth tables (i.e., they have the same truth values regardless of the truth values of its propositional variables). The notation “ ” denotes logical equivalence. portland maine expensive hotels
