Hence we can separate the numbers from the common unit, and replace 3 lb - I - 5 lb - 7 lb +2 lb by (3+5-7+2) lb, the additions and subtractions being then performed by means of an addition-table.

00This rule as to using brackets is not always observed, the convention sometimes adopted being that multiplications or divisions are to be performed before additions or subtractions.

00(vii.) The only exception that may be made to the above rule is that an expression involving multiplication-dots only, or a simple fraction written with the solidus, may have the brackets omitted for additions or subtractions, provided the figures are so spaced as to prevent misunderstanding.

00by a series of subtractions.

00(vi) Distributive Law, that multiplications and divisions may be distributed over additions and subtractions, e.g.

00Additions and subtractions are simple.

008d., on the grouping system, we split up each quantity into its denominations, perform the subtractions independently, and then regroup the results as the " remainder " £6, 2s.

00Of the two kinds of division, although the idea of partition is perhaps the more elementary, the process of measuring is the easier to perform, since it is equivalent to a F series of subtractions.

00Starting from the dividend, we in theory keep on subtracting the unit, and count the number of subtractions that have to be performed until nothing is left.

00(i.) Additions and subtractions are performed from left to right.

00(i.) The logical result of the commutative law, applied to a succession of additions and subtractions, is to produce a negative quantity-3s.

00Additions and a lot of the other functions are usually printed in black while subtractions are printed in red.
