... We have already met equations such as x2 = -1 whose roots are clearly not real since when squared they give –1 as the result. The imaginary number I, defined to be solution to the equation x2 = -1, is a basis of this new set. The imaginary unit i ...

Homework 2
... Ok, so things are vaguely looking up: 4 and the rest of the primes share the property that they aren’t divisible by things bigger than 2; also 2 has something to do with Fibonacci numbers, and we can restate (∗) equivalently as: (∗∗) If n is divisible by something bigger than 2, then Fn is composite ...

Elementary mathematics
Elementary mathematics consists of mathematics topics frequently taught at the primary or secondary school levels. The most basic topics in elementary mathematics are arithmetic and geometry. Beginning in the last decades of the 20th century, there has been an increased emphasis on problem solving. Elementary mathematics is used in everyday life in such activities as making change, cooking, buying and selling stock, and gambling. It is also an essential first step on the path to understanding science.In secondary school, the main topics in elementary mathematics are algebra and trigonometry. Calculus, even though it is often taught to advanced secondary school students, is usually considered college level mathematics.
