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
Example of Equality
6 x 8(= 48) is same as 12 x 4(= 48)
The number of trees in both the figures is equal.
