48. SUBTRACTION.

Take 2 m. 5 fur. 4 yds. 10 in. from 12 m. 28 po. 2 yds. 1 ft. 4 in.

Arrange the sum as in addition, putting the greater measure at the top. Begin to subtract at the right-hand side. 10 in. cannot be taken from 4in., 12 0 28 2 1

m. fur. p. yds. ft. in.

4

2 5 0 4 0 10 9 3 27 30 6

so one of the next greater measure, that is, 1 ft. or 12 in., must be added to the 4 in., making 16 in., and when the 10 in. are taken from 16 in., we have 6 in. left; put 6 in. in the place of the inches, and carry 1 ft. Next, the 1 ft. carried must be added to the 0, making 1 foot still, and this 1 ft. taken from 1 ft. leaves nothing; put a O in the place of the feet. Next, 4 yds. cannot be taken from 2 yds., so add 1 p. to the top, making 7 yds., and 4 yds. from 73 yds. leaves 3 yds.; put 3 yds. and carry 1 pole. The 1 p. carried, added to the O, is still 1 p., and taken from 28 p. leaves 27 p. Next, 5 fur. cannot be taken from 0, so add 1 mile to the top, making 8 fur., 5 fur. from 8 fur. leaves 3 fur.; put 3 fur. and carry 1 mile. Lastly, 1 m. and 2m. are 3 m., and this 3 m. taken from 12 m. leaves 9m., and the whole answer is 9 m. 3fur. 27 p. 34 yds. 6 in.
