求 详细步骤 (简算)

Answer 1

=-(8+3/17)*(14+13/15)-4*[-(14+13/15)]+[-(4+3/17)]*[+(2+2/15)]
=-(8+3/17)*(14+13/15)+4*(14+13/15)-(4+3/17)*(2+2/15)
=-(8+3/17-4)*(14+13/15)-(4+3/17)*(2+2/15)
=-(4+3/17)*(14+13/15)-(4+3/17)*(2+2/15)
=-(4+3/17)*(14+13/15+2+2/15)
=-(4+3/17)*(16+1)
=-(4+3/17)*17
=-(4*17+3/17*17)
=-(68+3)
=-71
