Answer:
(a) 51
(b) 13
(c) 134
(d) 38
(e) 3
(f) -88
Step-by-step explanation:
(a) 17 -8 + 42
= (17+42) - 8
= 59 - 8
= 51
(b) 18 - 7 + 4 - 5 + 3
= (18+4+3) - (7+5)
= (22+3) -12
= 25 - 12
= 13
(c) 22 × 8 - 42
= 176 - 42
= 134
(d) 50 - 10 - 5 + 3
= (50+3) - (10+5)
= 53 - 15
= 38
(e) 11 - 9 - 3 + 4
= (11+4) - (9+3)
= 15 - 12
= 3
(f) 82 +76 - 123 × 2
= (82+76)-(123×2)
= 158 - 246
= -(246-158)
= - 88

Answer:
Step-by-step explanation:
17-8+42 = 51
18-7+4-5+3 = 13
22* 8-42 = 134
50 - 10 - 5 + 3 = 38
11 - 9 -3 + 4 = 3
82 + 76 - 123 * 2 = -88
