COMPOUND ADDITION. 43 



1, Add up the figures in the lowest denomination, and 

 find how many ones of the next higher denomination are 

 contained in their sum, 



3, Write down the remainder, and carry the ones to the 

 next denomination ; with which proceed as before ; and 

 so on, through all the denominations to the highest, whose 

 sum must be all written down ; and this sum, together 

 with the several remainders, is the total sum required. 



The method of proof is the same as in simple addition.

equal to 4 in the farthings ; i in the shillings, to 1 2 in the pence ; 

 and I in the pounds, to 20 in the shillings ; therefore, carrying as 

 directed, is nothing more than providing a method of digesting 

 the money, arising from each column, properly in the scale of de- 

 non^ations ; and this reasoning will hold good in the addition of 

 compound numbers of any denomination whatever.
