原式=12.5×1.36×0.82×10.1
=12.5×1.36×[0.82×(10+0.1)]
=12.5×1.36×[8.2+0.082]
=12.5×1.36×8.282
=12.5×(1+0.4-0.04)×8.282
=[12.5+5+0.5]×8.282
=17×8.282
=8.282×(20-3)
=8.282×20-8.282×3
=165.64-24.846
=140.794

12.5X1.36X0.82X10.1
=(12.5X0.8)X1.36X10.1+(12.5X0.02)X1.36X10.1
=10X1.36X10+10X1.36X0.1+0.25X1.36X10.1
=136+1.36+10.1X1.36X1/4
=137.36+10.1X0.34
=137.36+3.434
=140.794
