Equality
Definition of Equality

• Equality is a state in which two things or values are always equal.

More about Equality

• In the state of equality, both values on the left and the right side of the sign ‘=’ will be the same.
• The equality “A is equal to B” is written as “A = B”.
• If a number is added on both sides of an equality, then the value of the expression or equation remains the same i.e. if c is any real number, then x + c = y + c
• If a number is subtracted from both sides of an equality, then the value of the expression or equation remains the same i.e. if c is any real number, then x - c = y - c
• If a number is multiplied on both sides of an equality, then the value of the expression or equation remains the same i.e. if c is any real number, then x · c = y · c.
• If a number divides both sides of an equality, then the value of the expression or equation remains same i.e. if c is any real number, then

Examples of Equality

• 6 x 8(= 48) is same as 12 x 4(= 48).

• The number of trees in both the figures is equal.

Solved Example on Equality
