It depends what base you are in.
We almost always use base 10, but in base 3, 1 plus 1 could equal 3.

Not true. The base 3 equivalents of the first few decimals is:
010 = 03
110 = 13
210 = 23
310 = 103
410 = 113
So 1 +1 is still not three and it will not become so simply by changing the base. 1 plus 1 can equal 3 if you redefine the operation "plus".
-1
They both are the same. They both equal 4.
1
-3 +1 = -2
When you are using non-standard definitions of "plus" and "minus", or of "equal".
4
It is: 1/3 plus 1/3 = 2/3
In mathematics, the problem 1 plus 2 is equal to 3.
No, 1 + 2 + 3 + 4 + 5 = 15.
35
3-cubed plus 2 plus 1 plus 4= 34
The answer to that question is infact .................. 24 .
