4*2.3+18.4*11.1+22.2*11.2
4*2.3+18.4*11.1+22.2*11.2
44.4*2.3+18.4*11.1+22.2*11.2
=44.4*2.3+4.6*(4*11.1)+(22.2*2)*5.6
=44.4*(2.3+4.6+5.6)
=44.4*12.5
=11.1*(4*12.5)
=11.1*50
=555
=11.4*4*2.3+18.4*11.1+11.1*2*11.2
=11.1*(9.2+18.4+22.4)
=11.1*50
=555
44.4*2.3+18.4*11.1+22.2*11.2
=11.1*4*2.3+18.4*11.1+11.1*2*11.2
=11.1*(4*2.3+18.4+2*11.2)
=11.1*(9.2+18.4+22.4)
=11.1*50=555
44.4*2.3+18.4*11.1+22.2*11.2
=44.4*2.3+4.6*(4*11.1)+(22.2*2)*5.6
