Question

Which of the following sign should always be there in an equation:
A.\[ = \]
B.\[ \ne \]
C.\[ > \]
D.\[ < \]

Answer 1

Hint: We will understand the equations. We will also understand inequalities. And then we will identify the sign that is always present in an equation. And hence, we will know the answer.

Complete step-by-step answer:
An equation can be defined as a mathematical statement consisting of an equal symbol between two algebraic expressions that have the same value. For example, \[x + 2 = 3y\] is an equation.
An inequality is a relation which makes a non-equal comparison between two mathematical expressions \[ \ne , < , > , \leqslant , \geqslant \] are the inequality symbols. For example, \[x + 5 > x - 2\] is an inequality.
Hence, we can say that equal to i.e. \[ = \] sign should always be there in an equation.
Hence, option (A) is the correct option.

Note: Equations are used by us in daily life problems. Using equations, we can solve problems like finding the area of a field when its dimensions are given.
An equation is a mathematical representation of two things which are equal.
