About X-Squared Sample

X-Squared is a math card where players solve math puzzles. This is the Sample version of X-Squared Challenge. The sample version contains a limited number of specially selected puzzles that require players to use 4 integer cards and 3 operator cards to produce a randomly selected solution card. This game is unique in that it requires players to "create" equations rather than solve them. It requires creative reasoning in order to solve the math puzzles. The math puzzles are both challenging and entertaining. Most of all, the game promotes enhanced learning for students and others in practicing their understanding of the order of operations and math facts. Anyone who plays the game, regardless of their current level of mathematics, will improve their basic math skills. By playing the game for just one hour players will see an immediate improvement in math skills.

The X-Squared Challenge game was derived from a patented product called the X-Squared Math Card Deck, produced by Cognitive Card Games LLC. That order of operations deck is the only one available in the world to the public that has two important characteristics: it's both simple and complete. The elements of the card deck are easy to use and understand in creating equations that conform to the rules of the order of operations. It is complete in that it includes all of the elements of the order of operations (PEMDAS): it has parentheses cards, exponent cards, multiplication cards, division cards, addition cards and subtraction cards. The parentheses and exponent cards are transparent so that they can overlay integer cards. The X-Squared Challenge sample app incorporates all of the characteristics of the card deck.
