Yet another wonderful numbers puzzle from Alok Mittal’s Mathematical Circles class. Not too difficult, and yet a lot of fun!
Take 10 cards of the same suite from Ace (A) through 10, i.e. essentially numbers 1-10. Using each card exactly once, construct a card frame (like the one shown below), where each side adds up to the same number.
Happy arranging!
2 10 6
3 5
7 4
8 9 1
Numbers are not adding up to be the same across sides
