A page that knows where it met you.
Only coarse request metadata is shown. This demo does not display or persist visitor IP addresses.
This template illustrates the basic operations of elementary mathematics. Place this navbar at the bottom of pages that are linked.
This template's initial visibility currently defaults to autocollapse, meaning that if there is another collapsible item on the page (a navbox, sidebar, or table with the collapsible attribute), it is hidden apart from its title bar; if not, it is fully visible.
To change this template's initial visibility, the |state=parameter may be used:
{{Elementary arithmetic|state=collapsed}} will show the template collapsed, i.e. hidden apart from its title bar.
{{Elementary arithmetic|state=expanded}} will show the template expanded, i.e. fully visible.
