7.32*3.2-2.4 74*0.72+4.3 0.8*(12.5+1.25) 5.2*10.1简便计算
7.32*3.2-2.4
=23.424-2.4
=21.024
74*0.72+4.3
=53.28+4.3
=57.28
0.8*(12.5+1.25)
=0.8*12.5+0.8*1.25
=11-1
=10
5.2*10.1
=5.2*10+5.2*0.1
=52+0.52
=52.52

14-7.32-2.68
=14-(7.32+2.68)
=14-10
=4
0.8×(4.3×1.25)
=0.8×1.25×4.3
=1×4.3
=4.3
1.23+3.4-0.23+6.6
=1.23-0.23+(3.4+6.6)
=1+10
=11
28.6×101-28.6
=28.6×(101-1)
=28.6×100
=2860
