Re: Can I perform calculations directly in django tags/filters?

Try using django-mathfilters.

No. You can add or subtract using the 'add' filter:
{{ width:add:"-5" }}
but anything else will require a custom template tag or filter.
Luckily, these are extremely easy to write:

@register.filter
def multiply(value, arg}
    return int(value) * int(arg)

{{ width|multiply:12 }}

You'll want to add error checking and so on of course, but that's the
idea.
