Most favorite part of Sunday mornings – walk with Nikita on the tree covered dirt roads. Today’s topic de jure was GCF and LCM of three or four numbers. During the mile and half walk, I kept on pushing her with bigger and bigger numbers to see how much mental math she could do. Eventually, she picked up a twig and made a quick hash of it by writing down on the dirt road and solving it 🙂 I called foul. She said “Whatevs” !!!
