8.04＋17.94－9.94＝16.04
20.64＋9.24－0.64＝29.24
17.55＋1.69－3.55＝15.69
13.47＋5.17－4.47＝14.17
11.98＋6.14－6.98＝11.14

20.3＋6.66－7.3＝19.66
1.26ⅹ8.8+8.8x98.74
=8.8x(1.26+98.74)
=8.8x100
=880
1.26ⅹ8.8+8.8x98.74
=（1.26+98.74）ⅹ8.8
=100ⅹ8.8
=880
1.26ⅹ8.8+8.8x98.74
=8.8（1.26+98.74）
=8.8x100
=880
用乘法分配律，（98.74+1.26）*8.8=100*8.8=880
绛旓細=8.8(1.26+98.74)=8.8x100=880
