... Proof. For an ordered pair, consider the process of subtracting the smallest from largest (stop if equal). For example, (4, 5) 7→ (4, 1) and (7, 3) 7→ (4, 3). By the definition of Stern’s sequence, (a2n , a2n+1 ), (a2n+1 , a2n+2 ) 7−→ (an , an+1 ). Every relatively prime pair appears (if not, then t ...

... There is another important fact about the mathematical language which should be noticed. For all numbers a, b, and c a(b + c) = ab + ac and for all numbers a, r, and x a(r +x) = ar+ax state precisely the same fact that is stated by (2)^. That is, the particular letters that are used in a statement o ...

... • How do we compare object variables for equality? – Answer: We use the object’s .equals method – Example: if (str.equals(“quit”)); • Question: Why the difference? Answer: Because == will compare where in memory the object is and not its contents. Note: There is more to this, but for now, this expla ...

... Thus, by the argument of the proof of Theorem 2.1 we may finally conclude with the following estimate. Lemma 3.7. Let λs be defined as in the statement of the corollary to Theorem 2.1. Then under the same hypotheses as in the statement of Theorem 2.1, for each k ≥ 4 and s ≥ 2 we have Us (P, H, P η ) ...

... If two numbers have factors (or divisors) in common, then the largest of these common factors is called their highest common factor (HCF). For example: 18 has the factors 1, 2, 3, 6, 9 and 18; 30 has the factors 1, 2, 3, 5, 6, 15, 30. Consequently, the numbers 1, 2, 3 and 6 are their common factors, ...

Law of large numbers
In probability theory, the law of large numbers (LLN) is a theorem that describes the result of performing the same experiment a large number of times. According to the law, the average of the results obtained from a large number of trials should be close to the expected value, and will tend to become closer as more trials are performed.The LLN is important because it ""guarantees"" stable long-term results for the averages of some random events. For example, while a casino may lose money in a single spin of the roulette wheel, its earnings will tend towards a predictable percentage over a large number of spins. Any winning streak by a player will eventually be overcome by the parameters of the game. It is important to remember that the LLN only applies (as the name indicates) when a large number of observations are considered. There is no principle that a small number of observations will coincide with the expected value or that a streak of one value will immediately be ""balanced"" by the others (see the gambler's fallacy)
