(Addition)
x=? y=? z=?

• since there is overflow (carried over) of y in MSB Y must be 1 because sum of 2 digit from 0,9 ranges to 0 to 18, so MSB must be 1
  
  Now consider the lsb we have x+y+z which should be equal to 10+x because the answer of LSB addition is z. so if addition of lsb is 1z the 1 would be carried over and z would remain in the asnwer
  
  eq1
  x+1+z = 10+z => x=9
  
  now
  consider the 4th term from right
  x+y+z +1 = 10+x
  (+1 because carry is being taken from 3th term from right)
  (same logic)
  1+z+1 = 10
  z = 8
  
  ans x=9 y =1 z=8

• x=0, y=0, z=0
  
  there will be three equations from the above puzzle. which will all add up to 0, hence all the three has value= 0
