2. {{ Evaldemo|#expr:2*3 }} displays

   {{ #expr:2*3}} {{#ifeq: +|-|{{{2}}}|gives}} {{#expr:2*3}}

3. {{subst:evaldemo|subst=subst:|#expr:2*3}} gives:

   {{ subst:#expr:2*3}} gives 6

4. {{ Evaldemo|1=#expr:2+2=5 }} displays

   {{ #expr:2+2=5}} {{#ifeq: +|-|{{{2}}}|gives}} {{#expr:2+2=5}}

5. {{ Evaldemo|1=#expr:(2+2=4)|s== }} displays

   {{ #expr:(2+2=4)}} {{#ifeq: +|-|{{{2}}}|=}} {{#expr:(2+2=4)}}

6. {{ Evaldemo|urlencode:!|s== }} displays

   {{ urlencode:!}} {{#ifeq: +|-|{{{2}}}|=}} %21

7. {{ Evaldemo|uc:abc }} gives

   {{ uc:abc}} {{#ifeq: +|-|{{{2}}}|gives}} ABC

8. {{subst:Evaldemo|uc:Upper Case|subst=subst:}} substitutes

   {{ subst:uc:Upper Case}} gives UPPER CASE

   See Help:Substitution for several caveats wrt subst=subst:.

As always the expression (first parameter) cannot directly contain "|", "=", plus other special cases related to square brackets / curly braces. In the case of this template "not directly" means "never" except from "=" as shown above.

For simple nested expressions use Template:Evdn (edit talk links history):

1. {{ evdn|#expr:4*|#expr:not 0| >3 | s=yields }} displays

   {{ #expr: 4*{{ #expr:not 0}} >3 }} {{#ifeq: yields|yields|yields|gives}} {{#expr: 4*{{#expr:not 0}} >3 }}

2. {{ evdn|urlencode:|DIRMARK }} displays

   {{ urlencode:{{ DIRMARK}}}} {{#ifeq: +|-|{{{s}}}|gives}} %E2%80%8E
