12. -12 + 4 – 3 + 7
13. 0,4 – 1,9
14. -1,3 + 2,7

Jawaban
(1) Persamaan = -3 + 2 – 5
= -6
(2) Persamaan = 6 + 7 – 13
= 0
(3) Persamaan = -6 – 1 – 3 + 8
= -2
(4) -5
(5) 3
(6) -11
(7) 0
(8) -14
(9) -4
(10) -7
(11) 6
(12) -4
(13) -1,5
(14) 1,4
(15) -1
(16) Persamaan = 8/18 – 15/8 = – 7/18
(17) Persamaan = -2 – 10 – 6
= -18
(18) Persamaan = 13 – 2 – 5 + 7
= 13
(19) Persamaan = -7 – 8 + 3 + 9
= -3
(20) Persamaan = 1 – 0,6 – 0,8
= -0,4
(21) Persamaan = – 2/6 + 1/6 + 4/6 = 1/2
