Balance the following redox reaction in basic solution:
O3 + Br- --> O2 + BrO3-

I know that Br is oxidized and O is reduced. However, why do we balance O3 --> O2 in the reduction reaction? Both have an oxidation number of 0 so I don't understand how to balance it.

You have to balance them because there are different numbers of O atoms. When balancing redox reactions, you balance both charge and atoms. In redox reactions, oxygen is balanced by adding H2O.
