SUBTR

CHAP. III.

SUBTRACTION.

UBTRACTION is the taking a lesser number from a greater, and thereby finding the remainder or dif

ference between them.

To prove Subtraction.

Rule.

Add the remainder to the lesser given number, and if the sum come the same with the greater given number, the work is right.

TABLE of SUBTRACTION.

1 2 3 4 5 6 7 8 9

0 1 2 3 4 3 0 7 8

The manner of using this table is the same with that of addition, only instead of adding the. figures together, subtract them.

Questions and Practical Examples.

2. What is Subtraction?

A. Subtraction from a greater take a less,

And thereby shews the difference or excess.
2. How are the numbers to be placed?
A. The less beneath the greater we dispose,
Units and tens in correpondent rows.

2. How is Subtraction performed?

4. Take ones from ones, and tens by tens decrease, If still the figures to subtract are less ;

But

But if the lower figure's greater, then
The lower figure we deduct from ten,
To what remains the upper figure add,
The just remainder of that place is had;
To the next lower figure carry one,

And thus from place to place the work is done,
