SIMPLE DIVISION SUMS.

The has "been sent to me as two. methods of doing 1 division sums, the first to show the easy proof not known to all, the latter to show the short method advo-cated-in -the upper classes, and appreciated by business men: — 6053 6053 986 15968347 - 986 | 5968347 • 5916 5234 . 3047 / 5234 / , 4930. - , , - 89 3047 - 2958 • - - 89 1 ' "\ - 5968347 The first is proved by adding th© three products 5916, 4930, 2958, and the remainder (89).' The. second is worked like this: The 6 of the quotient being obtained, the division is multiplied and the^ubtraction done in one operation — 6 si*es are 36 and 2 are 38; put down the 2. Six eights ate 48, and 3 are 51 and 5 are 56; put down the 5, making the remainder 52. Bring down the 3, and as the division is not contained in the new dividend 523, put 0 in the qut-ienfc and bring down the 4. The divisor goes *five times. Five sixes axe. 30, and 4 *are 34; put down the ,4. "Eive eighte are 40/* and 3 are 43; : the unit being a 3 to be. taken from a 3, put down. 0 and carry 4. -"Five nines are 45, and 4are 49vari"d'3 are 52; put down the. 3,\ snaking - the* remainder 304. Bring down the .7; iand the divisor goes 3 'times. -Three sixes are '-18, and --9 are 27; put down B, and carry 2. Three eights are 24, and 2 are 26 and 8 are 34; put down the 8. Three, nines are 27, and 3 are 30. As nothing is required to make up the 30 to be subtracted from, the sum is finished ; and is done in. less time and occupies less space. If you "haven't tried this method, , Eec how you like it.

■ Commercial arithmetic is now being taken at the Technical Classes, and as short methods are practised there I hope that as many as can will attend the commercial arithmetic — and, indeed, all other classes.

I did intend before this to bring these classes under the notice of my readers, junior and senior. Many cannot attend owing to distance or the hours subjects are taken. Why not, when possible, arrange .with teachers for copies of notes, and enrol as students working by correspondence. American schools of correspondence are greatly in vogue, though we have our technical schools and syndicates in Auckland and Christchurch who teach by correspondence, and 1 whose lessons are, as far as they are organised, better adapted to New Zealand requirements. Distance, however, lends enchantment to the view.
