Statement: a, b, a+b, a - b are all coprime integers.
Justification of the statement:
There exista one prime p such that p|a
Since p|a and p doesnot divide b then p cannot divide (a + b).
By similar argument p does not divide(a - b).
Consequently, a, b, a + b, a - b are all coprime integers.
Any comment about the ccorrectness of the Statement will be
