 boodler Apr 20, 2012 Please explain "The sum of the digits in the ones period is 12." To my way of thinking the answer, given the number, is 4. Terminology seems to have changed a great deal since I was at skule(!) dishagarg Jun 08, 2012 i too m waitin 4 an xplanation for"sum of digits in one's period"...ny1 plzzz do da honours... LuisFlaqqo Jul 06, 2012 how is the ones place 12 though? spikethru4 Nov 28, 2012 I'm thinking "the ones period" means the three least significant digits, i.e. the ones, tens and hundreds places. But I've never heard that terminology before and I have a maths degree! Once that was deciphered, the teaser was easy.
