RULE FOR ADDITION. 1. Write the numbers one under another, units under units, tens under tens, hundreds under hundreds, etc. 2. Begin at the right-hand or units' column, and add each column separately. 3. When the sum of a column is less than ten, write it under the column added. 4. Where the sum of a column is 10, or more, write the units' figure under the column added, and add the remaining figure or figures to the next higher order. 5. When the last column is added, set down the whole amount. Proof. Repetition is the only proof of addition. 42 FIRST LESSONS IN NUMBERS. SUBTRACTION. LESSON I. Subtraction is the process of finding the differ- ence between two numbers. The Difference, or remainder, is the number lef fc after subtracting. The Minuend is the number from which the subtraction is made. FIRST LESSONS IN NUMBERS. 43 The Subtrahend is the number to be subtracted. The Sign of Subtraction is a short horizontal line , called minus, which means less. It shows that the number on the right is to be taken from the number on the left. LESSON II. Principle.

Seven units from 5 units can- not be taken ; we must take one 248 Am. ten from the ten's figure and add it to the 5 units, which makes 15 units. 7 units from 15 units leave 8 units, which we write under units' place, because it is units. 3. Since we took i ten from the 7 tens, there are 6 tens left ; and 2 tens from 6 tens leave 4 tens, which we write under tens' place, because it is tens. 4. Three hundreds from 5 hundreds leave 2 hundreds. Hence the remainder is 248. NOTE. i. Take one from the next figure : do not bor- row and pay back. 2.

RULE FOR SUBTRACTION". 1. Write the less number wider the greater, units under units, tens under tens, etc. 2. Begin at the right or units' place, and sub- tract each figure of the longer number from the one above it, setting the remainder under the column subtracted. 3. If the lower figure Is greater than the upper figure, increase the latter by ten, and consider the next higher figure one less ; then subtract. Proof. The sum of the remainder and subtra- hend should equal the minuend. FTI?ST .LKHHOXS r.v Nr MULTIPLICATION. LESSON I. Multiplication is the process of taking one of two numbers as many times as there are units in the other. The Multiplicand is the number to be multi- plied.

A Circle is a plane figure bounded by a curve line, every point of which is equally distant from a point within, called the centre. A Circumference is the curve line which bounds the circle. The circumference is 3j- times the diameter. An Arc is any part of the circumference. A Radius is any straight line drawn from the centre to the circumference. A Diameter is a straight line drawn through the centre, and terminated both ways by the circum- ference. An Angle is the difference in the direction of two lines drawn f 1:0111 the same point, called the Vortex. Circular, or Angular Measure is used in measur- ing angles and arcs of circles. It is used in astronomy, geography, navigation, surveying, and for calculating difference of time.
