Is it possible to solve 30 by direct sum?
Firstly I will show you it is not possible by direct sum, then I’ll demonstrate the different ways to do so. If you take the numbers to be modulo 2, five odd numbers would sum up to 1, but 30 is 0 modulo 2 Prerequisites:- Knowledge of basic Mathematics. . . . For all x,y,z ∈ 2n+1 where n∈N (Natural numbers). Proof:-here’s no combination.
