Answer 2

（9-6+4）+0.5+0.85-0.13=8.22 （1.29+0.71）+（3.7+6.3）=12
13-（4+5）+0.7-（0.92+0.08)=3.7 （75-5）+360/20=88
13*（28+72）=1300 2300/4/25=23
（100+20+2）*88=8800+1760 265*（105-5)=26500

=440=11000 38*（99+1）=3800
13.25+1.75-（4.4+5.6）=5 (100+2)*12=1200+24=1224

Answer 3

9.5+4.85-6.13
=14.35-6.13
=8.22
13.7-4.92-5.08
=13.7-(4.92+5.08)
=13.7-10
=3.7
13×28+13×72
=13×(28+72)
=13×100
=1300
125×88
=125×8×11
=1000×11
=11000
13.25-4.4+1.75-5.6
=(13.27+1.75)-(4.4+5.6)
=15-10
=5
1.29+3.7+0.71+6.3

=(1.29+0.71)+(3.7+6.3)
=2+10
=12
