On a problem of mathematical fraction If the reduction result of a fraction is a + 2 / 3, then the value range of a is a ≠ - 3, then 1 / 2 of A-2 appears in the reduction process (or the original formula), then does the value range consider 2?

Yes, but if 2 is brought into the original formula, it is a + 2 / 3. Generally, the answer is not written in the case of 2 alone
