ADDITION of COMPOUND QUANTITIES. ADdition of compound quantities teacheth to add feveral fums, of different denominations, into one total fum. Write the fums in fuch a manner that the fame denominations may ftand under each other, obferving to place units below units, tens below tens, &c. and that the lowest denomination be fet on the right hand of your work, and fo on regularly to the left hand as the denominations increase in value. Then draw a line under them, and add up the figures in the loweft denomination first, and find how many of the next higher denomination are contained in the fum. Set down the remainder, and carry the ones found to the next denomination.Proceed in this manner till you have gone through all the denominations, obferving that the highest denomi nation is to be added by the rule for addition of fimple quantities. Begin at the top of the fum, and reckon the figures downwards, in the fame manner as they were reckoned upwards, and if the fum comes the fame as before, it is fuppofed to be right. 10.
