5×0.3×0.2 5.2×6-10 6.8-0.8×4 9.8-0.6+3.2 0.6×0.5×1.13 8.25+2.4×0.5 12.8-4.8×0.25 20×1.95-1.8 7.5+2.5×5.2 102×0.45 4.3×0.25×0.4 50.8×101-50.8 7.8×0.36-0.64×7.8 8×0.9×1.25 0.4×(2.5+25) 2.4+7.6×3.4 14.25×14.6-4.25×1...

4/7+1/14-1/2 =8/14+1/14-7/14 =2/14 =1/7 5/3-3/8-5/8 =5/3-(3/8+5/8) =5/3-1 =2/3 3/5+3/11+7/5+11 =(3/5+7/5)+11+3/11 =2+11+2/11 =13又2/11 3/4-{5/6-1/3} =3/4-(5/6-2/6) =3/4-1/2 =3/4-2/4 =1/4

(1.25+2.5)×3.2 =1.25×3.2+2.5×3.2 =1.25×8×0.4+2.5×4×0.8 =10×0.4+10×0.8 =4+8 =12
