The square or second power of a number, is, that number multiplied by itself; the cube or third power of any number, is its square or second power multiplied by that number; and the fourth, fifth or other power of any number, is the number produced, by the continual multiplication of that number repeated a certain number of times as a factor; thus 2x2=4 is the second power or square of 2, and is written 22 or 22; 3x3x3=27 is the third power or cube of 3, written 31 or 33, and 4x4x4x4=256 is the fourth power of 4, written 4]+ or 44, &c.

53. In 47cwt how many quarters ?

54. In 27cwt 2qrs 121b how many pounds ?*

As 112 pounds are in a Cwt. by multiplying the Cwts, by 12, removing the product, two places to the right for the hundreds, adding in the odd pounds of the quarters and pounds, this may be effected as readily as by any other method

[blocks in formation]

By the contracted method of multiplying by 112, 113, &c, as already noticed in this work, Cwts qrs and lbs may be brought into pounds in one line, by mentally adding in the pounds of the odd weight, together with the addition of the first and second past figures; a little practice will render this perfectly easy

In the first example I say, twice 7 are 14 and 8 are 22, put down 2 and carry 2; again twice 2 are 4 and 6 are 10, and 2 to carry are 12 and 7 the back figure are 19, put down 9 and carry 1; 1 and 2 are 3, and 7 are 10 put down 0, and carry 1, and finally 1 and 2 are 3,

In the second example, twice 3 are 6 and 6 are 12, put down 2 and carry 1; twice 4 are 8, and 1 to carry are 9, 4 the tens figure of the pounds and 3 the back figure are 16, put down 6 and carry 1; twice 1 are 2 and 4 and 3 the back figures with the one to carry are 10, put down 0 and carry 1; twice 1 are two and I to carry together with 1 and 4 the back figures are 8, and none to carry; 1 and 1 are 2, the back figures put down 2, and finally annex 1 the last figure.

The same may be effected by addition only, and I believe with as little liability of error as either of the former, and perhaps less. Write the given number of Cwts four times, the two first exactly under each other, units under units tens under tens &c, each of the other lines one place removed to the left and add in the pounds contained in the odd weight if any, EXAMPLES.
