以下是100道简便运算题，包括小数脱式计算。

4.6-1.85+2.08=4.28+0.73-3.375-(4.19-2.83)=4.71+0.1-

4.71+0.18=8.41-(4.19-2.83)=4.2+3.27-4.49=12-5.18-3.82=

12-(5.18+3.82)=14.22+(4.45+5.55)=7.3+5.6+2.7=196.75-

(16.75+120)=14.72+0.28-14.72+0.28=6.44+8.9+3.86=36.28-

0.83-4.17=12.29-(4.29+6.43)=17.83-9.5-7.83=45.55-

(15.55+6.8)=4.45+14.22+5.55=9.12-4.6-2.4=17.7-13.88-

4.12+4.3=4.83+2.71+5.17+2.29=12.13+34.52+17.87=

0.28+3.6+0.72+6.4=0.516+0.25+0.48=19.36+0.79-10.36=

12.5+3.35+2.75+4.65=18.47-6.96+0.53-0.04=14.83-5.99=

4.8+7.26+5.44=17.68-3.5+2.32-6.53=3.8+4.65-7.02=0.9+0.71

=12.76-5.8+0.24=34.45-(15.18-7.86)=9.87-(6.87+2.5)=

4.3×2.1-7.6=7.8÷[12.5-(1.9+6.7)]=7.5×16.3+7.5×3.7=

3.08×101-3.08=19.73-0.01×97-8.03=5.4÷[1.5×(4.3-3.7)]=

3.7×19.08-3.7×9.08=12.5×9.7×0.8=50-7.9×5.3=

3.25×[10.8÷(7.2-5.4)]=1.25×4.3×2.4=4.75×17.5+2.5×4.75=

0.22×1.5+0.92÷2.3=4.05=0.04×12.7×250=87=7.2÷0.9-1.2×5

=2.5
