(-16)-(-12)-24-(18)这条数学题怎么解
(-16)-(-12)-24-(18)这条数学题怎么解

(-16)-(-12)-24-(18)这条数学题怎么解
(-16)-(-12)-24-(18)
=(-16)+12+(-24)+18
=【(-16)+(-24)】+(12+18)
==【(-40)+30】
=-10

(-16)-(-12)-24-(18)
=-16+12-24-18
=12-16-18-24
=-4-18-24
=-22-24
=-46
如果你最后一项是-(-18)而不是-(18)的话,那么
(-16)-(-12)-24-(-18)
=-16+12-24+18
=-4-24+18
=-28+18
=-10

(-16)-(-12)-24-(18)
=-16+12-24-(18)
=-4-24-(18)
=-28-18
=-46

=(12+18)-(16+24)
=30-40
=-10
