（1）7.36-5.4+1.74-1.6
（2）3.6×1.2÷3.6×1.2
（3）8×0.37+1.63÷0.125
（4）100-4.05÷0.36-2.5×5
（5）[（4.3-2.01）+2.2]÷4
（6）（1.72+1.72+1.72+1.72）÷3.2×2.5．
（1）7.36-5.4+1.74-1.6
=（7.36+1.74）-（5.4+1.6）
=9-7
=2；
（2）3.6×1.2÷3.6×1.2
=3.6÷3.6×1.2×1.2
=1×1.2×1.2
=1.44；
（3）8×0.37+1.63÷0.125
=8×0.37+1.63×8
=8×（0.37+1.63）
=8×2
=16；
（4）100-4.05÷0.36-2.5×5
=100-11.25-12.5
=100-（11.25+12.5）
=100-23.75
=76.25；
（5）[（4.3-2.01）+2.2]÷4
=[2.29+2.2]÷4
=0.09÷4
=0.0225；
（6）（1.72+1.72+1.72+1.72）÷3.2×2.5
=1.72×4÷3.2×2.5
=1.72×（4×2.5）÷3.2
=1.72×10÷3.2
=17.2÷3.2
=5.375．
