Answer 1

430-250= 0.17+0.06= 1.02-0.09= 7200÷800= 0.17+0.6=

0.83-0.6= 17×300= 0.98-0.09= 0.2+0.78= 600×700=

10.2+0.02= 0.15+0.7= 670+250= 10.2+0.2= 9.2-6=

8500÷500= 3.2-3.2= 3.7+2.3= 25×100= 3.2-0.32=

2+2.8= 380-290= 0.35+0.5= 0.35+0.63= 3500÷70=

3.1+3= 3.8+0.38= 7500÷250= 3.8+1= 0.95-0.05=

450+780= 3.1+0.3= 3+0.3= 630÷9= 4.5-0.4=

9.5-5= 330×9= 9.53-1.53= 9.5-0.5= 3.5+2.4=

1-0.95= 0.3+0.27= 0.47+0.13= 4.5+4= 4-0.6=

0.95+0.05= 2.5+3.2= 0.74+0.16= 23×100= 9.8-4.8=

480÷40= 0.53÷100= 5.1+2.3= 125×80= 0.078÷10=

0.52+0.4= 70×12= 0.25×100= 3.4-2.8= 0.6-0.37=

0.052×10= 10+0.08= 1-0.75= 0.5×1000= 7.82+0.3=

13.5+6.5= 3.05×100= 1.2-0.8= 21.6-12.6= 63÷100=

0.83-0.5= 0.76+0.14= 80÷1000= 2.7+0.4= 0.72-0.43=

30×100= 0.92-0.2= 3.5+4.8= 3.5+2.4= 5+0.07=

1-0.61= 0.47+0.23= 0.25+0.75= 3.7+0.33= 0.51+0.33=

1-0.6= 8-4.6= 5.8-3.6= 0.52+0.4= 6.45+5.5=

4.5-1.3= 3.4-2.8= 9.53-1.53= 8.8-6.7= 10+0.08=

9.5-7.3= 7.2+0.8= 7.82+0.3= 8.8-6.7= 9.5-7.3=

1-0.95= 3.4-2.8= 0.96-0.35= 9.53-1.53= 0.25+0.75=

1.2-0.8= 0.83-0.5= 2.7+0.4 5.6＋5.6×9= 4×(1.5＋0.25) =

24÷4＋56×0.25= 0.5÷0.5÷0.5＝ 1.2×0.4＋0.4×1.3= 0.5×2÷0.5×2=

0.32÷0.2+1= 0.01÷0.1+0.1= 1÷0.1－0.1÷1= 0.68×1.9+0.32×1.9＝

0.9+0.1÷0.1＝ 2.5×（4＋0.4）= 0.8-0.8×0.5＝ 0.8÷0.8×0.5＝

5.4÷1.8-1.8＝ 11.2-1.93+0.8＝ 2.1×0.3÷2.1＝ 0.125×8－0.1=

14×0.25×4= 15-3.2-4.8= 2.6+9.8+3.4= 19×0.7+0.7=
