ARITHMETIC.

ARITHMETIC is that part of the Mathematics which teaches the art of computation by numbers.

All operations in Arithmetic are performed by means of the following figures

Cipher One Two Three Four Five Six Seven Eight Nine
0, 1, 2, 3, 4, 5, 6, 7, 8, 9.

NUMERATION.

Numeration teaches the proper disposition of figures to express any proposed number, when that number is too great to be expressed by a single figure.

When a number is expressed by more than one figure, the value of each figure is determined by the situation which it holds in relation to the others, as represented in the following

table.
