ANSWER:
1 + 1 = 2
Explanation:
1 added to 1 is 2 because adding +1 adds a number.
ex:
3+1= 4
you should memories the number sequence like
1 2 3 4 5 6 7 and so on.
the number sequence adds 1 to become 2 the 2 added to 1 will be 3
it will be easier if you memories the number sequence . no need to count:)
