1. Quote of this month: "When I die, I want to die like my grandfather who died peacefully in his sleep. Not screaming like all the passengers in his car." - Will Rogers

2. New challenge AQQ296 about repairing an equation in a digital display:

A digital system expresses the equation (10+1) * (10-1) = 101 on a dots
matrix display. The equation is obviously incorrect.
By witching off, 2 dots in that display, it is possible to validate the equation.

Which dots are you changing and what's the equation you obtain?

Good luck and try to be among the first ones!
