简便计算：1、6.3-（4.98-0.7）2、32.7/25/43、8.29-（2.29+1.9）4、0.25*32*1.25

1. 6.3-(4.98-0.7)
=6.3+0.7-4.98
= 7-4.98
=2.02
2. 32.7÷25÷4=32.7÷（25×4）=32.7×100=3270
3. 8.29-（2.29+1.9）
=8.29-2.29-1.9
=6-2+0.1
=4+0.1
=4.1
4. 0.25×32×1.25
=0.25×4×（8×1.25）
=1×10
=10

1、
6.3-（4.98-0.7）
= 6.3-4.98+0.7
= 6.3+0.7-4.98
= 7-(5-0.02)
= 7-5+0.02
= 2+0.02
= 2.02
2、
32.7/25/4
= 32.7/(25*4)
= 32.7/100
= 0.327
3、
8.29-（2.29+1.9）
= 8.29-2.29-1.9
= 6+1.9
= 7.9
4、
0.25*32*1.25
= 0.25*(4*8)*1.25
= (0.25*4)*(8*1.25)
= 1*10
= 10
