%N Decimal expansion of the sum of sqrt(2) and sqrt(5) with no positional regrouping.

%C a(n) is the sum of A002193(n) and A002163(n) without "carrying" (regrouping) when sum is greater than 9.

%H G. C. Greubel, <a href="/A294671/b294671.txt">Table of n, a(n) for n = 1..10000</a>

%F a(n) = A002193(n) + A002163(n).

%e for n = 8: A002193(8) = 5, A002163(8) = 9 -> a(8) = 14.

%t Total[RealDigits[#, 10, 120][[1]] & /@ {Sqrt@ 2, Sqrt@ 5}] (* _Michael De Vlieger_, Nov 13 2017 *)

%Y Cf. A002193, A002163, A073212, A294670.
