HP 10s+ Easter Egg (Statistics) - Eddie W. Shore - 04-10-2013

When in statistics mode, the HP 10s+ stores the sums into the its registers:

A = $x^2

B = $x

C = n

D = $y^2

E = $y

F = $xy

X = $x^2y

Y = $x^4

Where $ stands for Sigma.

The values can be recalled the same way as pressing [SHIFT] [ 1 ]. I wonder if it works the same way with the Casio fx-300ms (don't have the 300ms on me).

The 115MS does not do this. (I also don't have a 300 to check.)
