Discrete …Generally speaking, a homomorphism between two algebraic objects A,B A,B is a function f \colon A \to B f: A → B which preserves the algebraic structure on A A and B. B. That is, if elements in A A satisfy some algebraic equation involving addition or multiplication, their images in B B satisfy the same algebraic equation.Division Definition If a and b are integers with a 6= 0, then a divides b if there exists an integer c such that b = ac. When a divides b we write ajb.

The smallest topology has two open sets, the empty set emptyset and X. The largest topology contains all subsets as open sets, and is called the discrete topology. In particular, every point in X is an open set in the discrete topology.The positive integers are $\mathbb Z^+=\{1,2,3,\dots\}$, and it's always like that. The natural numbers have different definitions depending on the book, sometimes the natural numbers is just the postivite integers $\mathbb N=\mathbb Z^+$, but other times the natural numbers are actually the non-negative numbers $\mathbb N=\{0,1,2,\dots\}$.The letters R, Q, N, and Z refers to a set of numbers such that: R = real numbers includes all real number [-inf, inf] Q= rational numbers ( numbers written as ratio) N = Natural numbers (all ...

Both integers a a and b b can be positive or negative, and b b could even be 0. The only restriction is a ≠ 0 a ≠ 0. In addition, q q must be an integer.

Discrete Mathematics is a term that is often used for those mathematical subjects which are utterly essential to computer science, but which computer scientists needn’t dive too deeply into. But Khan Academy doesn’t cover this in its core mathematics, which culminates in the harder (IMO) calculus subjects, it must be admitted. ...See Range:.

When we speak of …A one-to-one function is also called an injection, and we call a function injective if it is one-to-one. A function that is not one-to-one is referred to as many-to-one. The contrapositive of this definition is: A function f: A → B is one-to-one if x1 ≠ x2 ⇒ f(x1) ≠ f(x2) Any function is either one-to-one or many-to-one.
