100*(0,01+,0,02+0,03+...0,09)=100*0,045=45
5,8*1,4+5,8*3,6+5,8*3,2+5,8*1,8=5,8*(1,4+3,6+3,2+1,8)=5,8*10=58

2,4*52,3+2,4*47,7=2,4*(52,3+47,7)=2,4*100=240
17.05^2-17,05*7,05=17,05*(17,05-7,05)=17,05*10=170,5
2,7^2-2,7*+1,7^2=7,29-2,7+2.89=4,59+2.89=7,48
1,4^2+2,744:1,4=1,96+1,96=1,96^2=3,8416


0,01=0,1^2
