REVIEW IN ADDITION.

An indefinite number of problems in Addition can be made from the following circle of figures:

1. Commencing at any letter in the outer circle, the pupil adds three, four, or more numbers towards the right or towards the left, as indicated by the teacher; thus, commencing at A, and adding towards the right, he says, 7, 11, 13, 21, 24, etc.; adding towards the left, he says, 7, 12, 13, 21, 24, 27, etc.

2. Commencing at a particular letter, the pupil adds the number against that letter in the outer circle to the successive numbers of the inner circle; or, commencing at a number of the inner circle, he adds to it the successive numbers of the outer circle.

3. The teacher mentions some number, and the pupil adds to it the numbers of either circle, commencing at the different letters. For example, the teacher mentions 15: the pupil commencing at A, in the outer circle, and adding towards the right, says, 15, 22, 26, 28, 36, etc.
