There are two primary rules by which all operations in Arithmetic are performed: namely, Addition and Subtraction.

ADDITION.

THE use of Addition is to ascertain the amount of two or more numbers when put together.

Rule.

1. Set down any one of the numbers, and place under it all the rest, in such a manner, that units may stand under units, tens under tens, hundreds under hundreds, and so on; and draw a line under the last.

2. Begin at the right hand, or units' column, and add together all the figures contained in that column.

3. Consider all the figures contained in the amount of the column, and set down under it all above an even number of tens, and carry one for every ten to the next column, proceeding in the same manner until all the columns have been added up, setting down the whole amount of the last column.

Proof.-Perform the addition downwards; and if the amount is the same as when added upwards, the work is right.

Questions.

How many primary rules are there in Arithmetic, and what are they called?

For what is Addition used?

How do you set down numbers which you intend to add together?

Do you commence at the right or left-hand column of numbers which you wish to add together?

When you have found the amount of all the figures contained in a column, how do you proceed? How do you prove Addition?

Addition Table.

To use the table, look in the outside left-hand column for one of the numbers to be added, and in the top column for the other number; then in the square opposite the one, and under the other, their sum will be found.

Note.-If the pupil is required to commit the foregoing table to memory, his progress will be thereby very much

facilitated.

MULTIPLICATION.

MULTIPLICATION is a short method of performing Addition, when the same quantity is required to be added a given number of times.

There are three parts in Multiplication: viz.

The sum to be multiplied is called the Multiplicand. The sum by which you multiply is called the Multiplier. The result of the operation is called the Product. The Multiplicand and Multiplier are likewise called both together Factors, or that by which the operation is performed.
