Writing Proofs
... Theorem 4. Let n be a positive integer. Then n is even if and only if n2 is even. Proof. We have to write TWO PROOFS. “⇒.” (In this part, we’ll use a direct proof to show that if n is even, then n2 is even.) Suppose that n is even. This means that n = 2k for some integer k. Therefore n2 = 4k 2 . Sin ...

Prime numbers and factorizations
... Prime numbers and factorizations: The definition of prime number you probably vaguely remember from some math class is that the number is divisible by exactly two numbers: itself and one. That’s kind of cool, but there’s more to prime numbers than that. The really useful thing about prime numbers is ...

... The letters I, V, X, L, C, D, M were of Etruscan origin and one speculates that the Etruscan numerals derive from tally marks or resemble hand signs. The subtractive principle like 9 = IX, 90 = XC were hardly used by the Romans. They would write V IIII, LIIII instead. Problem 6 . How would you write ...
