Answer»

Answer:

(a) 51

(b) 13

(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

= 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
