-3/4+(-20.125)-6.5+1/8-(-0.75)-5.29+3.1-(-1.8)+(-0.1)-9.87
-3/4+(-20.125)-6.5+1/8-(-0.75)
=0.75-20.125-6.5+0.125-0.75
=(0.75-0.75)+(0.125-20.125)-6.5
=0-20-6.5
=-26.5
-5.29+3.1-(-1.8)+(-0.1)-9.87
=-5.29+3.1+1.8-0.1-9.87
=-10.36

所有的关键都4!=24 !为阶乘 1.3.4.6 6/3-1=1 4!=24 24*1=24 1.5.5.5 (5-1)!=24 5/5=1 24*1=24 1.6.6.8 (6 6-8)

—26.5
