Question

(230 +765) – 30
(1271 + 2699) – 1071
(27 + 1039) – 39
(32 + 1028) – 1018
452 – (352 + 29)
389 – (57 + 189)
8963 – (963 + 500​

Answer 1

• (230 + 765) - 30 = 230 + 765 - 30 = 965
• (1271 + 2699) - 1071 = 1271 + 2699 - 1071 = 2899
• (27 + 1039) - 39 = 27 + 1039 - 39 = 1027
• (32 + 1028) - 1018 = 32 + 1028 - 1018 = 42
• 452 - (352 + 29) = 452 - 352 - 29 = 71
• 389 - (57 - 189) = 389 - 57 - 189 = 143
• 8963 - (963 + 500) = 8963 - 963 - 500 = 7500
