COMPOUND SUBTRACTION, TEACHES to find the difference, inequality, or excess, between

any two sums of diverse denominations. RULE.-Place those numbers under each other, which are of the same denomination, the less being below the greater ; begin with the least denomination, and if it exceed the figure over it, borrow as niany units as make one of the next greater ; subtract it therefrom; and to the difference add the upper figure, remembering always to add one to the next superior denomination for that which you borrowed. NOTE. The method of proof is the same as iu snaple subtraction.
