There is an operation program, can make a ⊕ B = n (n is a constant), get (a + 1) ⊕ B = n + 1, a ⊕ (B + 1) = n-2=______ .

There is an operation program, can make a ⊕ B = n (n is a constant), get (a + 1) ⊕ B = n + 1, a ⊕ (B + 1) = n-2=______ .

⊙ 1 ⊕ 1 = 2 (where a = 1, B = 1, n = 2) ⊕ 2 ⊕ 1 = 3, 2 ⊕ 2 = 1 (where a = 2, B = 2, n = 1), 3 ⊕ 2 = 2, 3 ⊕ 3 = 0 (where a = 3, B = 3, n = 0) ⊕ 4 ⊕ 3 = 14 ⊕ 4 = - 15 ⊕ 5 = - 2 Therefore, the answer is - 2006
