Let a and b be any real number then

if u add o to any real number a then--

a+0=a it means a-a=0

again when u subtract  0 from a

u will get a again
...

a-0=a
it again indicates a-a=0

if u multiply a with 0 u ll get

a*0=0  it means 0/0=a(new formula found)

other intresting formulae
a/a=1..
..
a+b=b+a..
