7. Assume that A is a subset of a metric space (X, d). Show that the interior points of A are the exterior points of AC, and that the exterior points of A are the interior points of AC. Check that the boundary points of A are the boundary points of Ac 8. Let (X, d) be a metric space, and let A be a subset of X. We shall consider A with the subset metric dA a) Assume that G C A is open in (X, d). Show that G is open in (A, dA) b) Find an example which shows that although G C A is open in (A, dA) it need not be open in (X, dx). c) Show that if A is an open set in (X, dx), then a subset G of A is open in (A, dA) if and only if it is open in (X, dx)

Algebraic Expressions

In mathematics, an algebraic expression consists of constant(s), variable(s), and mathematical operators. It is made up of terms.

Numbers

Numbers are some measures used for counting. They can be compared one with another to know its position in the number line and determine which one is greater or lesser than the other.

Subtraction

Before we begin to understand the subtraction of algebraic expressions, we need to list out a few things that form the basis of algebra.

Addition
