Problem to solve
2 + 3 = 10
8 + 4 = 96
7 + 2 = 63
6 + 5 = 66
9 + 5 = ?
Solution to problem:
2 + 3 = 10 (2+3=5(2))
8 + 4 = 96 (8+4=12(8))
7 + 2 = 63 (7+2=9(7))
6 + 5 = 66 (6+5=11(6))
9 + 5 = ? (9+5=14(9))
9 + 5 = 126
this point is not met and the order matters of factors in this problem, the result is not the same.
This time this point is not met because the result set given in the problem are not equal to the sum of any factor.
At this point I think it's obviously not apply to what is being done on the problem
A group is a set G which has defined an internal composition law that satisfies the above axioms.
Then this, problem is not a group because don´t meets with some requeriments, do as explain his definition.
This is of wikipedia now i try explain of the pdf of Elisa Schaeffer:
e°g = g°e = g
this is not true since we have to
a(a + b) = c
a(a + e) is different from c
so if there is no identity, can not be reversed and also used "e"
the associativity is not because we
a (a + b) = c
Not the same that
b (b + a) = c
this point is correct because it says that if g ° h belongs to G
And that g, h belongs to G
If you multiply
You get a whole number
Then we come to the same conclusion on this problem is not a group
Well, I hope that the result is the desired and sorry for my bad english.
