Zero

Zero
Zero may be defined for the present,as the absence of any magnitude.It is obtained by subtracting a number from another which is exactly equal to itself.4-4=0.
IMPORTANT PROPERTIES OF ZERO 
1. 0+0 =0 ;  x+ 0 =x ; -x+0= -x

2.0-0=0 ; x-0=x ; -x-0=-x


we understand that x+ 0 = x- 0 ∴ +0 = - 0

3. 0 x 0 = 0 ; x x 0= 0 ; 0 x x = 0 .

4 . 0➗ x = 0

5. x➗ 0 is infinite when xキ0 ( i.e. x is not equal to zero ) and 0 ➗ 0 is an indeterminate result.

6. 0 square = 0 x 0 =0 
Thus zero raised to any power is equal to zero and consequently any root of zero is equal to zero.

integral numbers divisible by 2 are called even numbers

integral numbers not divisible by 2 are called odd numbers

in working examples the positive root is usually taken.
