Yet another example could be similar figures, such as squares. In college math courses, we’re introduced to modular operations. Before ...

The di↵erence between two sets A \ B is the set of elements in A but not in B. The complement of a set A with respect to a set ⌦ is Ac = ⌦ \ A (we may o ...

... Warm-Up! 1. We are asked to determine the value of the sum 1 + 2 + 3 +  + 98 + 99. Adding pairs of these addends, we notice a pattern. For example, pairing the first and last numbers, we have 1 + 99 = 100. Then pairing the second number with the next to last number, we see that 2 + 98 = 100. We wil ...

... The significance of Russell's paradox can be seen once it is realized that, using classical logic, all sentences follow from a contradiction. For example, assuming both P and ~P, any arbitrary proposition, Q, can be proved as follows: from P we obtain P Q by the rule of Addition; then from P Q and ~ ...

In fact all the integers of the form p + 5, being p a prime, can be written as p + 2 + 3 as well. In this way one provides an infinite family of integers admitting at ...

... Mathematical Logic is the study of the type of reasoning done by mathematicians. (i.e. proofs, as opposed to observation) Axioms are the first unprovable laws. They are statements about certain “basic concepts” (undefined first concepts). There is usually some sort of “soft” justification for believ ...
