... (d) If x ≡ a (mod m) and x ≡ a (mod n), then x ≡ a (mod mn). False. 5 ≡ 35 (mod 6) and 5 ≡ 35 (mod 10), but 5 6≡ 35 (mod 60). SALVAGE: True if (m, n) = 1. Proof. By hypothesis we have m | x − a and n | x − a. Since (m, n) = 1, this implies that mn | x − a =⇒ , which is what we want to show. ...

... From Le Veque [3] or Roberts [4], we have the following theorems. Hurwitzfs theorem states that, if a is irrational and 3 = 19 there are infinitely many irreducible rational solutions to (1). Dirichletfs theorem states that, if 3=v5/2, then all rational solutions to (1) are convergents to a* Since l ...

... However, we need to start with the basics and work our way up because we need to make sure that we have GREAT fundamentals in math. In other words, we need to know WHY we do things other than “That’s what my teacher told me to do.” Why do we subtract the three? Next question: why do we subtract the ...

Letter to the Editor
... I'm afraid there was an error in the February issue of The Fibonacci Quarterly. Mr. Shallit's proof that phi is irrational is correct up to the point where he claims that 1/0 can't be an integer. He has no basis for making that claim, as 0 was defined as a rational number, not an integer. The proof ...

List of important publications in mathematics
This is a list of important publications in mathematics, organized by field.Some reasons why a particular publication might be regarded as important:Topic creator – A publication that created a new topicBreakthrough – A publication that changed scientific knowledge significantlyInfluence – A publication which has significantly influenced the world or has had a massive impact on the teaching of mathematics. Among published compilations of important publications in mathematics are Landmark writings in Western mathematics 1640–1940 by Ivor Grattan-Guinness and A Source Book in Mathematics by David Eugene Smith.
