(Just about all posts are transcribed rapidly after I make the movies for them–please let me know if there are any typos/errors and I’ll right them, thanks).
1 + 1 + 1 + 1 + 1
1 + 1 + 1 + 1 + 1
1 + 1 × 0 + 1 = ?
A big a part of the dialogue is what the proper expression is. Some individuals imagine you must wrap round every line to the subsequent, appending the characters like so:
1 + 1 + 1 + 1 + 11 + 1 + 1 + 1 + 11 + 1 × 0 + 1 = ?
Others suppose you must put a plus image between strains
1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 × 0 + 1 = ?
I believe these interpretations are flawed, since you can not break up a single quantity by a line break. And you can not merely insert a plus image for no motive.
The interpretation that is smart to me is to simply consider the very third line.
1 + 1 × 0 + 1 = ?
We should do multiplication first, so now we have:
1 + 1 × 0 + 1
= 1 + 0 + 1
= 2
I counsel that is the proper reply primarily based on how the puzzle is written.
