Very good exercise... But I can't find out the correct solution. In many cases this wuould be incorect. Otherwise this can be correct when we violate mathematical rules. It will be same like I can say 2+2=5 and this is true while violating mathematical rules. (2+2) at square = 25 4+ 8 + 4 = 25 16 = 25 4 = 5 2+2 = 5

Lol , your formula is wrong but i will try to solve it for you :) Lets say that first one (1)+1 = -1 this one wont be number (its will be var) and its will have the value of -2 now lets back to solve this (-2)+1 = -1 now this is correct , but if you incessant on solving it its can be write this 1+1+1 = 3 otherwise you would be talking about 1=0 and that's wrong :)

1+1=-1 1+1+1=-1+1(taking +1 in the both side) 3=0 1+1+1=0 1+1=-1(proved)[UNDERSTAND & THIS IS RIGHT]

Even i think you misunderstand me , and i couldn't understand your either ;) i will try to solve your question again (in case its solvable) your question is lil tricky :) anyway maybe you showed me the answer but i think this way can solve and prove 1+1 = -1 1+1=-1 (multiply both sides) 1+1 = 1 (multiply all with 2) 2+2 = 2 (collecting them) 4 = 2 (taking the sqrt for the left side) sqrt(4) = 2 (now here how the answer come to be 2) now we know thats 2 comes from 1 (after we multiply it) So we will find 1+1 = 1 or 1+1 = -1 (we used sqrt thats why there is two answers) and in this case we will take 1+1=-1 :)
