EACH CARD HAS A MAIN NUMBER VALUE AND 5 NUMBERS BELOW: The bottom numbers are PRODUCTS in the multiplication tables from 0x0 to 12x12. There are 5 numbers on each card, so that you can find each number on several cards, making it easier to match cards and make calculations.

BETTER THAN FLASH CARDS - PLAY INSTEAD OF SITTING ALONE: Choose two cards, e.g. Red 11 and Green 12. Multiply the main numbers and match them with a third card, e.g. Yellow 10, with the product 132 among the 5 numbers below the line. Make more triples like this. Who can find more?
