Math Solitaire – How quickly can you solve basic math sums in your head? Play as one player alone, or play against the computer in this straight-forward, challenging and addicting math card game for kids, teens and adults too. The history of this Solitaire game began with traditional Solitaire where you first remove all Jokers from the 54 cards and then you are given 4 random cards from the remaining 50 cards. In this version of the Math Solitaire game, you receive five random cards and you have to operate (play) with the first 4 cards, using addition, subtraction, multiplication and division. Each card must be used once in total although their order does not matter.
For example, you receive the following five cards: 1, 3, 9, 7, 5. You must now come to a total sum of 5 by operating the 4 first cards (1, 3, 9, 7). This can be achieved in a number of ways but our example would be: (1 + 7) – (9/ 3) = 5. There might be some rare cases with no possible solution but the chance of getting such cards is less than 14%. The intermediate results cannot be a fraction. For example, (1/3 + 3) × 3 = 10 is not a valid solution for such cards: 3, 3, 3, 1, 10. It should be 3+3+3+1=10.
You have to choose the game mode at the start (to play the game alone or play against the computer). Playing against the computer has 2 advantages:
a) you see good solution examples when you are stuck (as you are playing the same cards as the computer is)
b) you are put under time pressure because computer does not stop thinking and it thinks fast! You may play 10, 20 or 30 turns in a match against the computer.
Once you choose the game mode, you are brought to the game area. You start the game by clicking the NEXT TURN button in the bottom right corner of the game screen, in order to receive 5 random cards. The sum total (result) you have to come to is the value of the fifth card (the green one). Click on two cards and select the math operator – addition, subtraction, multiplication or division. There are no negative numbers, and therefore there is no difference in which order the cards are selected. If you decide to change your mind – simply click on the operator sign again and deselect the cards. They will be put back and you can use them again.
