原式=6.2*0.38+6.2*0.61+6.2
=6.2*(0.38+0.61+1)
=6.2*1.99
=6.2*(2-0.01)
=12.4-0.062
=12.338
=6.2*(0.38+0.61+1)
=6.2*1.99
=6.2*(2-0.01)
=12.4-0.062
=12.338

原式=6.2ⅹ0.38+6.2x0.61+6.2x1
=6.2ⅹ(0.38+0.61+1)
=6.2ⅹ1.99
=6.2x(2-0.01)
=12.4-0.062
=12.338
=6.2ⅹ(0.38+0.61+1)
=6.2ⅹ1.99
=6.2x(2-0.01)

简便计算为
0.62*3.8+6.2*0.61+6.2
=6.2*0.38+6.2*0.61+6.2
=6.2*(0.38+0.61+1)
=6.2*1.99
=12.338
0.62*3.8+6.2*0.61+6.2
=6.2*0.38+6.2*0.61+6.2
=6.2*(0.38+0.61+1)
=6.2*1.99
=12.338
