60 ARITHMETIC.
62 is contained in 10,240 A. 165 times and 10 A, remain-
ing. We write 165 A. under the 10,240 A. in the dividend
and reduce 10 A. to sq. rd. In 1 A. there are 160 sq. rd.,
and in 10 A. there are 10 X 160 = 1,600 sq. rd. 62 is con-
tained in 1,600 sq. rd. 25 times and 50 sq. rd. remaining.
We write 25 sq. rd. in the quotient and reduce 50 sq. rd. to
sq. yd. In 1 sq. rd. there are 30 j sq. yd., and in 50 sq. rd.
there are 50 times 30 j sq. yd. = 1,512^ sq. yd. 62 is con-
tained in 1,512— sq. yd. 24 times and 24— sq. yd. remaining.
11 In 1 sq. yd. there are 9 sq. ft., and in 24— sq. yd. there are

24- X 9 = 220- sq. ft. 62 is contained in 220- sq.ft. 3 times
and 34- sq. ft. remaining. We write 3 sq, ft. in the quo-
tient and reduce 34— sq. ft. to sq. in. In 1 sq. ft. there are
144 sq. in., and in 34- sq. ft. there are 34- X 144 = 4,968
/V A)
sq. in. 62 is contained in 4,968 sq. in. 80 times and 8 sq. in.
remaining.
We write 80 sq. in. in the quotient.
It should be borne in mind that it is only for the purpose
of illustrating the method that this problem is carried out
to square inches. It is not customary to reduce any lower
than square rods in calculating the area of a farm.
(118) To square a number, we must multiply the
number -by itself once, that is, use the number twice as a
factqr.
Ans.
Thus, the second power of 108 is 108 X 108 = 11,664.
