"One sandwich"

Translation: Un panino

[merlinvaughan]

Yes - I think thats a bit unfair - maybe supply an explanation as to why it would be better to use 'un' as opposed to 'uno'.

[mwhel]

This says "one sandwich," not "a sandwich"

[ivan.is.here]

Because asking for "a sandwich" is basically asking for "one sandwich."

[MABBY]

First time ever for "One" in a lesson. One is uno. A counting number.

I agree, this says one sandwich, not a sandwich Duolingo should offer explanation.
