content: According to text at the bottom of the table, it was designed: “For use with any form of instruction. For minus cover. For plus point to a 5 then 2 more, for 5 plus 2 equals 7. For FORM A Ten, the number required to form a ten for the larger digit is taken from the smaller digit. For USE A TEN, the number uncovered shows the number left, hence the number to be added to the other digit.
