2
if you add 1+1 it = 2 get it :D
If you add 0.39 to 0.61 you get 1
Add.
You cannot add 3x and 1. You can add 3x and x and get 4x though.
1 and a half add 1 and two thirds = 2
It is: 33+211+1 = 245
add 9 add 1 subtract 20 add 9 add 1
because if you add 1 to 12 you will get one more not less.
12, 13, 16 Add three, then add 1, then add three, then add 1, and so on so forth

You start with 1 and add 1. add another 1 and another. In all, do the addition 9,999,999,999 times.
the next number in the sequence is 25............starting at the beginning, you add the odd numbers to the existing number to get the answer. Add "1" to 0, get 1; add "3" to 1, get 4; add "5" to 4, get 9; add "7" to 9 to get 16........and add "9" to 16 to get 25.........
