Irrational numbers: cannot be expressed as ratio, non-terminating and non-repeating decimal expansions - , and irrationals; any number with decimal expansion as opposed to. Inclusive (closed) interval from a to . b (a, b] Left exclusive (left open) interval from a to , not including a b. Right exclusive (right open) interval from a to , not including . b b (a, b) and is an element of x (a, b) x. Infinity can be used as an interval endpoint, but is always excluded as it is a limit, not a number: {x r | a < x < b} If and only if; first implies second, and second implies first. Therefore, x > 0 1 < 2x x < 0 1 > 2x x > 0 x < 0 and and.
