Answer 1

7.6*3.6+0.36*0.02-36*26%=76*0.36+0.36*0.02-0.36*26=0.36*（76+2-26）=0.36*（50+2）=0.36*50+0.36*2=18+0.72=18.72
0.8888*0.6+0.2222*7.6=0.2222*4*0.6+0.2222*7.6=0.2222*2.4+0.2222*7.6=0.2222*(2.4+7.6)=0.2222*10=2.222
56*1.02-1.4*0.8=4*14*1.02-14*0.08=14*(4.08-0.08)=14*4=56
2.4*20.6+33.1*7.6
=2.4*20.6+(20.6+12.5)*7.6=2.4*20.6+20.6*7.6+12.5*7.6=20.6*(2.4+7.6)+12.5*7.6=206+12.5*7.6=206+12.5*4*1.9=206+50*1.9=206+95=301
465*8.2+465*29.6-365*37.8=465*8.2+465*29.6-(465-100)*37.8=465*8.2+465*29.6-465*37.8+100*37.8=465*(8.2+29.6-37.8)+100*37.8=378
4.25*166-42.5*14.2+24*5.75=4.25*166-4.25*142+24*5.75=4.25*(166-142)+24*5.75=4.25*24+24*5.75=24*(4.25+5.75)=240
3.6*14.4+9.3*32+3.21*36=3.6*14.4+3.6*32.1+9.3*32=3.6*46.5+9.3*32=1.8*93+93*3.2=93*5=465
88888*66667+44444*66666=88888*66667+88888*33333=88888*（66667+33333）=8888800000
（256+725*255）/（256*725-469）=（256+725*255）/【256*725-（725-256）】=（256+725*255）/【725*255+256】=1
