@KalamCenter Since it's move 1 stick. Then move the stick from the top of 7 making the 7 to be 1, then take it to the top left of 3 to make 9. The resultant figure is 191.
@HonMoses_Kuria When I was in High School, our principal then dedicated Sunday to be students outing day, we could leave the school but on one condition , return by 6pm. So we knew we had every Sunday for a break from the school to explore surroundings, of course responsibly.
