I want to do a simple arithmetic operation in a .ss template.

<% loop $Images %>
    <img src="$Link" alt=""/>
    <% $Pos == 4 %>
        and {$TotalItems - 4} more foto's 
        $Break
    <% end_if %>
<% end_loop %>

For example I would want to output

and 10 more foto's

But the best I can get is

and 14 - 4 more foto's

I know I can make a function, which works for now, but can I do arithmetic operations in the template?

You could do it like this.

At first you limit the images to the amount you would like to display. After that you loop over the same set with an offset of x (4) and check if there's more. If so, output the amount of remaining images.

<% loop $Images.Limit(4,0) %>
   <img src="$Link" alt=""/>
<% end_loop %>
<% if $Images.Limit(9999,4) %>
  and $Images.Limit(9999,4).Count more foto's 
<% end_if %>

the code is untested but should work.

Edit

I think "real" arithmetic is not possible by default. You'll need to write a custom function to do this.
