Depends, are you talking about for labeling, expression evaluation or
template display?

For labeling: No.

For expression evaluation: Yes (using logical expressions you can do
EXPRESSION ([item1] + [item2] > 50)

For templates: Yes for HTML via javascript, e.g.:

<script ...>
  var total = [item1] + [item2];
  document.write(total);
</script>
