Use django-mathfilters. In addition to the built-in add filter, it provides filters to subtract, multiply, divide, and take the absolute value.
For the specific example above, you would use {{ 100|sub:object.article.rating_score }}.

Generally it is recommended you do this calculation in your view. Otherwise, you could use the add filter.
