1084. Знайдіть значення виразу:

1) 116 – 2415 = 1530 – 21630 = –11130;

2) –479 – 2512 = –42838 – 21536 = –64336 = –7736;

3) –78 – (–256) = –2124 + 22024 = –2124 + 14424 = 12324;

4) 1725 – (–1,25) = 128100 + 125100 = 253100 = 2,53;

5) –3,2 – (–2815) = –315 + 2815 = –3315 + 2815 = –21815 + 2815 = –23;

6) 38 – (–56) – 34 = 924 + 2024 – 1824 = 1124.

7) 412 – 312 – 413 + 523 = 1 + 113 = 213;

8) –5,4 – 115 + 3,4 – 730 + 2310 = –2 – 230 – 730 + 2930 = –2 + 2 = 0.
