We next remove the two balls on the second wire for a multiplier, and then remove two balls from the third wire, placing them exactly under the first two, which forms a square, and then say twice two are four, which every child will discern for himself, as he plainly perceives there are no more.

We then move three on the third wire, and place three from the fourth wire underneath them saying, twice three are six.

Remove the four on the fourth wire, and four on the fifth, place them as before and say, twice four are eight.

Remove five from the fifth wire, and five from the sixth wire underneath them, saying twice five are ten.

Remove six from the sixth wire, and six from the seventh wire underneath them and say, twice six are twelve.
