( + - )×(-36)
答案: 解: ( +12 )+( −8 )−( −4 ) =12-8+4 =8
解: −214−4−125−14+525 = −214−14+525−125−4 = −212+4−4 = −212
解: 8×(−34)×(−4)÷(−2) = 8×(−34)×(−4)×(−12) = −8×34×4×12 = −12
解: 3×(−4)+(−28)÷7 = −12−4 =-16
解: (−478)−(−512)−|−12|−(−18) = −478+512−12+18 = 18−478+5 = 14
解:( −13 + 12 - 19 )×(-36) =( 13 - 12 + 19 )×36 = 13 ×36- 12 ×36+ 19 ×36 =12-18+4 =-2
