What are strings?

Question

There is a recent tweet in which a lady said 1+2=12.

Answer 1

In programming, sequences of text are often called strings (a string of letters).

Now, we can treat 1+2 as numbers, in which case: the number one added to the number two equal the number three.

or we can treat it as text: the text “1” added to the text “2” results in the text “12”.
