4.58+25.1+45.8×6.35+8.458×114﹙简便运算﹚
4.58×25.1+45.8×6.35+0.458×114
=45.8×2.51+45.8×6.35+45.4×1.14
=45.8×(2.51+6.35+1.14)
=45.8×10
=458

4.58+25.1+45.8×6.35+0.458×114
=4.58+25.1+4.58*63.5+4.58*11.4
=4.58*(1+63.5+11.4)+25.1
=4.58*75.9+25.1
=4.58*(100-25.1)+25.1
=458-4.58*25.1+25.1
=458+25.1(1-4.58)
=458-25.1*3.58
=458-89.858
=368.142
