How does one say "It's not nothing."?

Question

In English, we can express the idea that something is not negative, such as:> A: What's in the box?> B: Oh, nothing.> A: **It's not nothing!**In English, the double negative (*not* and *nothing*) conveys the idea that we are negating the "noting" said by person B. In Spanish, though, double negatives don't work the same way. A word-for-word translation would result in:> A: **No es nada!**Which means "It is nothing" not "It is not nothing."The same phenomenon is found in other contexts, as well, any time we would intentionally use a double negative to indicate a positive (as opposed to when a double-negative is unintentionally used, as is also often done).How can one express the double-negative meaning that is present in the English original?

Answer 1

No, no es nada= "No es importante".
