It may be confusing to beginning mathematicians who have never seen it explained. The technique is this: If we wish to prove A ⇒ B, we can assume the truth of both A and not-B. From those two assumptions we deduce a contradiction; the contradiction demonstrates that indeed A ⇒ B....
$$$ Five Corners (1987) IMDB ** Very funny beginning to the movie, with a mathematics teacher grading, and failing, a stack of tests, and then being shot in the back with an arrow. Harold Jacobs' Geometry can be seen on the shelf. ...
The first mathematical symbols for arbitrary quantities appeared much later (beginning in the fifth and fourth centuries B.C.) in Greece. Quantities (areas, volumes, angles) were rep-resented in the form of segments, and the products of two arbitrary like quantities were given in the form of...
Perhaps later might come an appreciation of mathematical objects with inconsistent properties, as the truthmakers for preferred mathematical propositions, and a basis for model theory. But this metaphysical extra is certainly not necessary to make a beginning with. Hence, our starting point is ...

The topic of this paper is mathematical modelling or—as it is often, more broadly, called—applications and modelling. This has been an important topic in mathematics education during the last few decades, beginning with Pollak’s survey lecture (New Trends in Mathematics Teaching IV, Paris, pp...
