Integers, Rational, and Real Numbers
... The size of an integer, or the distance from zero of that integer along a number line is called the absolute value of that integer. | 1 | = 1 because 1 is one unit away from zero on a number line, but | -1 | = 1 also, because -1 is also one unit away from zero on a number line! In fact, 1 and -1 ar ...

... Suppose we have pairs (a, b) and (c, d) such that a ≤ c and b ≤ d. The weight of these pairs is max{(a+b), (c+d)} = c+d. If we swap b and d and make two new pairs (a, d) and (c, b), we get a pairing whose weight is max{(a+d), (c+b)}. Since a ≤ c, a+d ≤ c+d and since b ≤ d, c+b ≤ c+d. Thus, the new p ...

... Rational Numbers – are any integers that can be written as ratios or fraction. Irrational Numbers – are numbers that cannot be written as a quotient of two integers. Radicals (Square Roots) – If b2 = a, then b is a square root of a. Real Numbers – are the collection of all numbers, both rational and ...

... Theorem. Every sufficiently large even integer n > 46 can be expressed as the sum of abundant numbers a and b thus: a + b = n. Proof. First we rewrite n = 2x (where x is some positive integer) as n = 20m+r, where r satisfies n ≡ r mod 20 and m = n−r 20 . If r = 0, then we’re done, we can simply set ...
