  • 1. 15.762 ÷ 37 - 512 + 96 ×72
    =426 - 512 + 6912
    =6.826
    2.19×27 + 5.205 ÷15 - 269
    =513 + 347 - 569
    =291
    3.(-9) - 6 × (-72) : 16 -20
    =(-9)-6×(-4,5)-20
    =-9+27-20
    =-2
    4.168:((17-24) × (-19+15))
    =168÷((-7)×(-4))
    =168÷28
    =6
  • 1.)(15.762:37)-512+(96×72)=426-512+6.912=7.850
    2.) (19×27)+(5.205:15)-269=513+347-269=591
    3.) (-9)-(6×-72):16-20=(-9)-(-432:16)-20=(-9)-(-27)-20=(-9)+27-20=-2
    4.)168:(-7×-4)=168:28=6
