1 + 1 = 2 is an equation and hopefully the answer you are looking for.
"1 plus 1" has no variable, no "equals" sign, and no unknown. It's not an equation, and it asks no question. In order to come up with an "answer", one would first have invent a question. "1 plus 1" is at best an arithmetic expression with a numerical value of 2.
This will be in binary arithmetic, i.e. base 2 arithmetic.
Not in normal arithmetic.
In normal arithmetic it is equal to 2
When you are working in binary arithmetic.
Because "plus" has a specific meaning in arithmetic and it is not concatenation.
1 + 12 is not an equation.
