14.8*6.3-6.3*6.5+8.3*3.7
=6.3*(14.8-6.5)+8.3*3.7
=6.3*8.3+8.3*3.7
=8.3*(6.3+3.7)
=8.3*10
=83
=6.3*(14.8-6.5)+8.3*3.7
=6.3*8.3+8.3*3.7
=8.3*(6.3+3.7)
=8.3*10
=83

解:14.8×6.3-6.3×6.5+8.3×3.7
=6.3×(14.8-6.5)+8.3×3.7
=6.3×8.3+8.3×3.7
=8.3×(6.3+3.7)
=8.3×10
=83
=6.3×(14.8-6.5)+8.3×3.7
=6.3×8.3+8.3×3.7
=8.3×(6.3+3.7)
=8.3×10
=83

14.8*6.3-6.3*6.5+8.3*3.7
=6.3*(14.8-6.5+3.7)+2*3.7
=6.3*12+2*3.7
=6.3*10+2*(6.3+3.7)
=63+20
=83
=6.3*(14.8-6.5+3.7)+2*3.7
=6.3*12+2*3.7
=6.3*10+2*(6.3+3.7)
=63+20
