The long real line pastes together ℵ 1 * + ℵ 1 copies of the real line plus a single point (here ℵ 1 * denotes the reversed ordering of ℵ 1) to create an ordered set that is "locally" identical to the real numbers, but somehow longer; for instance, there is an order-preserving embedding of ℵ 1 in the long real line but not in the real ...
However, if one searches for real solutions, there are two solutions, √ 2 and – √ 2; in other words, the solution set is {√ 2, − √ 2}. When an equation contains several unknowns, and when one has several equations with more unknowns than equations, the solution set is often infinite. In this case, the solutions cannot be listed.
But clearly not all real numbers are solutions to the original equation. The problem is that multiplication by zero is not invertible : if we multiply by any nonzero value, we can reverse the step by dividing by the same value, but division by zero is not defined, so multiplication by zero cannot be reversed.
The RIEs are set up in 1963 by the Government of India in different parts covering various regions. The Regional Institutes were started with the objective of qualitative improvement of school education through innovative pre-service and in-service teacher education programs and relevant research, development, and extension activities.
The rationals are a dense subset of the real numbers; every real number has rational numbers arbitrarily close to it. [6] A related property is that rational numbers are the only numbers with finite expansions as regular continued fractions. [18] In the usual topology of the real numbers, the rationals are neither an open set nor a closed set. [19]

In mathematics, the solution set of a system of equations or inequality is the set of all its solutions, that is the values that satisfy all equations and inequalities. [1] Also, the solution set or the truth set of a statement or a predicate is the set of all values that satisfy it. If there is no solution, the solution set is the empty set. [2]
