Answer: -418, 728, 446, -429, 1159, -696

Step-by-step explanation:

1. $n = -199 - 219 = \boxed{-418}$ .

2. $m = 438 - (-290) = 438 + 290 = \boxed{728}$ .

3. $128 - (-318) = 128 + 318 = \boxed{446}$ .

4. The sum of 429 and 429 is $429+429 = 858$ . We need to subtract this from 429, so $429 - 858 = \boxed{-429}$ .

5. The sum of 510 and 319 is $510+319 = 829$ . Subtracting -330, we get $829 - (-330) = 829 + 330 = \boxed{1159}$ .

6. Call the unknown number " $\star$ ". Then $\star + 298 = -398$ , so $\star = -398 - 298 = \boxed{-696}$ . (Think about it.)
