Answer 2

Sure, let's solve the given expressions step by step:

№1130.

1. (1 + (84 - 208 + 25)) = (1 + (-124 + 25)) = (1 - 99) = -98
2. (2 - (45 - 69 - 21)) = (2 - (-45 + 69 + 21)) = (2 - 45 + 69 + 21) = 47
3. (3 - (284 - 49 - 244)) = (3 - (-284 + 49 + 244)) = (3 + 284 - 49 - 244) = -6
4. (4 + (86 - 98) + 42) = (4 - 12 + 42) = 34
5. (5 - (59 - 69) - 29) = (5 - (-10) - 29) = (5 + 10 - 29) = -14
6. (6 + (-38 - 410) + 38) = (6 - 38 - 410 + 38) = -404

№1131.

1. (119 + 141) - (-59 + 119) = 260
2. (325 + 219) - (125 + 119) = 300
3. (228 - 215) - (28 - 315) = 200
4. -(82 + 98) - (186 - 86) = -380
