Lattice Multiplication - Description

Description

A grid is drawn up, and each box is split diagonally. The first and second numbers are positioned along the top and right of the lattice respectively, with each digit being above a column, or next to a row. Simple products are written in each box, corresponding with numbers along the top and to the right of each box. For example, if the number above the box is 3, and the number to the right is 6, (for 18) will be written in the box. If the simple product lacks a tens place, simply fill in the tens place with a 0.

After all the boxes are filled in this manner, the diagonals are added from right to left, bottom to top, with the numbers added and written where the diagonal leads. When the sum contains more than one digit, the value of the tens place is carried over up to the next diagonal. Numbers are filled to the left and to the bottom of the grid, and the answer is the numbers read off down (on the left) and across (on the bottom).

Famous quotes containing the word description:

    Once a child has demonstrated his capacity for independent functioning in any area, his lapses into dependent behavior, even though temporary, make the mother feel that she is being taken advantage of....What only yesterday was a description of the child’s stage in life has become an indictment, a judgment.
    Elaine Heffner (20th century)

    I fancy it must be the quantity of animal food eaten by the English which renders their character insusceptible of civilisation. I suspect it is in their kitchens and not in their churches that their reformation must be worked, and that Missionaries of that description from [France] would avail more than those who should endeavor to tame them by precepts of religion or philosophy.
    Thomas Jefferson (1743–1826)

    The type of fig leaf which each culture employs to cover its social taboos offers a twofold description of its morality. It reveals that certain unacknowledged behavior exists and it suggests the form that such behavior takes.
    Freda Adler (b. 1934)
