NOTES. *The pupil may now be taught that the character +, which is called plus, is used to denote Addition, and shews that the numbers between which it stands are to be added together: thus 9+3 shews that nine is to be added to three. Two lines placed thus, signify equal to, therefore when we write 9+3=12, it is the same thing as saying in words, nine added to three are equal to twelve. Again 5-12 +4+9-30; that is, 5 and 12 and 4 and 9 being added together, are: equal to 30.. The learner must refer to the table of contents of his Bible, to ena-ble him to answer this and the two following examples. SUBTRACTION. BY SUBTRACTION we find the difference between two numbers.* Rule (1). Place the lesser number under the greater, so that units may stand under units, tens under tens, &c.; begin at the right hand, and take each figure in the_lower line from the figure above it, and set down the remainder. (2). If the figure in the lower line be the greater, add ten to the upper one, and then take the lower one from the sum, set down the remainder and carry one to the next lower figure, with which proceed as before. † (3). When the figure in the lower line is equal to that above it, the difference is nothing, for which a cypher must be set down. ‡ NOTES. *This character, called minus, when placed between any two numbers, denotes that the smaller number is to be subtracted, or taken from the larger: thus 9 -5 shews that 5 is to be taken from the 9, and we say, 954; that is, 5 subtracted from 9 is equal to 4. Again, 21504-136957809. + This operation is commonly called borrowing, and as ten in the right-hand line is equal to only one in that which precedes it on the left, one is only carried to that line. The pupil may ask why the one is added to the lower line, instead of diminishing the upper line by the ●ne borrowed? The question is very proper: and he will see, if he try it, that either mode of operation produces the same result; but the usual method is thought to be the best in practice: thus, if I have to take 28 from 45, I say 9 from 5 I cannot, but 8 from 15 and there remain 7, I carry 1 to the 2, and say, 3 from 4 and there remains 1; the answer is 17. It will be the same if I sav 8 from 15 and there remains 7, and then making the 4 into 3, by taking from it the one I borrowed, I say 2 from 3 and there remains 1; the answer is still 17. I See Table, p. 7, with explanation. MISCELLANEOUS EXAMPLES IN SUBTRACTION. Ex. 1. The invention of gunpowder was discovered in the year 1302: How long is is it since to the present year, 1811? 2.
