@Bobby Cole 1+1 can = 3 if you assume another factor is involved. 1(x) + 1=3 and we discover that factor to be 2. That is the absolute of algebra. If the teacher asked young Johnny to approach the board and solve 1+1= and Johnny answers 3 and the teacher says wrong and gives young J an F that would be justified since J made an assumption that wasn't indicated, however, if she says, "Interesting Johnny how did you arrive at your answer?" and young J writes out 1(2) + 1=3. then young J has just made what appeared his opinion a fact and an educational experience.
