(3.71+5.29)+(-2.74+ -0.26)+(4.7+6.3)=17
(176.2+348.3+252.5)+(42.47+382.23)=777+424.7=1201.7
(378.63-78.63)+(-5.72-4.28)=290
(0.625*1.6)+(0.625*26.4)+(0.625*52)+(0.625*20)=0.625*(1.6+26.4+52+20)=0.625*100=62.5
15.37*7.88-9.37*7.38+15.37*2.12-9.37*2.62=(15.37*7.88+15.37*2.12)+(-9.37*7.38-9.37*2.62)=15.37*10-9.37*10=(15.37-9.37)*10=60
4.65*32+4.65*25+4.65*43=4.65*(32+25+43)=4.65*100=465
15.48*35-15.48*19+15.48*84=15.48*(35-19+84)=15.48*100=1548
125*0.67875+125*6.875+125*0.53375=125*8=1000
