Hi,

1+1 is equal to 2. That is one plus one is equal to 2.

However most of the preprimary or primary teacher say 1 and 1 is 11. To help the little kids to write number 11 easily.

So teachers use to say 1 and 1, 11 at time of teaching so that student does not get confused and learn to write number without confusion.

But conceptually 1+1 is 2 and 10+1 is 11.

Hope it helps.
