Man, the advantage in the decision can be if the “+” image was value what it must be value, that is, the sum.
Nonetheless, it’s noticed that the only “downside” right here is the unusual idea that has “downside” and “solution” that designed this train. Right here is the other: we’re given the options, and we now have to invent the “downside” to acquire them. Due to this fact, that nonsense of “considering exterior the field” doesn’t imply something aside from giving the image “+” the worth “advert libitum” that fits us to make operations give these outcomes.
Because of this, there are quite a lot of readers right here who’re being proper, and the issues invented not only need to be two, however, with a little bit creativeness (which lacked the one who designed the “downside” and reduces it to 2 ) will be infinite. And if we “get out of the field” that is “out of the field” that we need to impose the designers of the issue, and picture that the image means a distinct factor in every operation? Effectively, if the settlement on the values of the indicators is damaged for what fits the one who invented the query, there isn’t a motive why it can’t be damaged for every little thing.
To start with, it’s occurring to me that if “1 + 4” and “2 + 5” and “3 + 6” are sums of numbers that are adopted, however instantly we leap to “8 + 11”, whose earlier quantity must be “7 + 10”, and the earlier one ought to be “6 + 9”, and the earlier one “5 + 8”, and the earlier one “4 + 5”, it’s completely logical that we have in mind the operations completed in all these steps are lacking, so reply 1 can be:
1 + 4 = 5
2 + 5 (+5) = 12
3 + 6 (+12) = 21
4 + 7 (+21) = 32
5 + 8 (+32) = 45
6 + 9 (+45) = 60
7 + 10 (+60) = 77
8 + 11 (+77) = 96 (and never 40, as you say).
Alternatively the identical may very well be mentioned of assigning the image “+” the that means that you place as a second solution:
1×4 = 4 + 1 = 5
2×5 = 10 + 2 = 12
3×6 = 18 + 3 = 21
4×7 = 18 + 4 = 21
5×8 = 18 + 5 = 21
6×9 = 18 + 6 = 21
7×10 = 18 + 7 = 21
8×11 = 88 + 8 = 96
So it will be that the solution on these two sides is similar.
