... Important: if a bijective correspondence exists between two finite sets, they have the same cardinality. To emphasise: Two sets have the same cardinality if �and only if) it is possible to match each element of A to an element of B in such a way that every element of each set has exactly one “partner ...

... Taught first class 43 years ago, still learning from my students MMT 400 Discussing place value, issue of why 100 = 1 and 10–n =1/10n. Students were very surprised (actually quite shocked) that I couldn’t give them a reason why these notations had to be defined in this way, that the definitions/nota ...

... 8. Let n > 1 be a positive integer. Suppose that 2n chess pieces are placed at distinct squares of an n × n chessboard. Show that four of these pieces determine the vertices of a parallelogram. Outline. Imagine each pair of pieces as determining a vector in the first or fourth quadrant. There are n( ...

Sets with a Negative Number of Elements
... Informally, we say f is a subset of g (and write f ⊆ g) if one can remove elements one at a time from g (never removing an element that is not a member of g) and thus either acheive f or have removed f . For example, we might start with the hybrid set f = {a, b, c, c|d, e}. We will remove a few of i ...
