The answer is the number 2 we know this because if we said 1 + 1 = 2 then we must find a way to prove it and the way to prove it is to go what 2-1=1 so there you go you have used the same numbers to make a different equation and now you have your oringinal answers that you used for adding that number is now your answer there you have it 1 + 1 = 2.
