C1:10 + 20 + 30 +40+50+60

=(10+60)+(20+50)+(30+40)

=70+70+70

=70.3=210

C2:10+20+30+40+50+60

=10.1+10.2+10.3+10.4+10.5+10.6

=10.(1+2+3+4+5+6)

=10.21=210

10 + 20 + 30 + 40 + 60 + 50

= 30 + 30 + 40 + 60 + 50

= 60 + 40 + 60 + 50

= 100 + 60 + 50

= 160 + 50

= 210

Vậy 10 + 20 + 30 + 40 + 60 + 50 = 210
