Whole numbers (W)

All natural numbers together with zero are called whole numbers, denoted by W. W = {0, 1, 2, 3, 4,......}

Integers (Z)

All whole numbers together with negatives of natural numbers are called integers, denoted by Z. Z = {.....-4,-3,-2,-1, 0.1.2, 3, 4,...} (i) -1, -2, -3, - 4,….. are called negative integers. (ii) 1,2,3,4 ... are called positive integers. Note: Zero is neither positive nor negative.

The numbers of the form -\[\frac{a}{b}\], where 'a' and 'b' are natural numbers are called fractions.

Linear Equations in One Variable

Equation: An equation is a statement of equality of two algebraic expressions involving one or more unknown quantities (variables).

Linear equation in one variable: If an equation involves only one variable and the highest index of power of that variable is 1, the equation is called a linear equation in one variable.

The general form of a linear equation in variable x is a\[x\]+ b = 0, a\[\ne \]0 or px = q, p \[\ne \]0

Laws of Equality

(i) The same quantity may be added to or subtracted from both sides of an equation without changing the equality. Thus, if a = b, a +c= b +c a - c= b – c (ii) If more...
