Jolly Jong is the Math Mahjong game, which consists in selecting the squares with the numbers so that they add/subtract/multiply the proposed amount on the left. The squares do not need to be next to each other. You can select any cell, and your goal is to add the proposed amount when the + symbol appears next to the number. Check the operator , and choose the two operands or numbers to get the given number with the proposed operation. If your answer is correct, more numbers will appear in the eliminated cells. Your goal is to do many mathematical operations correctly in this game similar to Mahjong in the arrangement of tiles, but with the focus on doing mathematical calculations online and practicing simple sums. Start with addition, then practice subtraction and other operations.
