Answer:
2.
Explanation:
Because you have 1 one, added by another 1, you get 2.
Sometimes calculators take too long to pull out. When you have a smaller math equation, you can do one of the most simplest ways to solve this. Using your fingers to count each 1 to get your answer would be a very quick way to find the sum or difference of what you are trying to find.
I hope this helps.
