Balancing Equations?

This is the Problem (the subscripts should be smaller but i can't do that):

CaCl2 + Na2CO3 ->

and this is what I got for my answer :

2 CaCl2 + 2 Na2CO3 -> Ca2(CO3)2 + 4 NaCl

My question is does the two subscrips for Ca and CO3 to the right of the arrow cancel out because they're the same?? I can't remember. Thanks
