absolute value
I don't understand "The absolute value of a number is always positive or zero"... can someone explain more?
 * This is the way you should walk from zero up to the number's point or otherwise. Agree: you can't walk any "minus-way". Negativity and positivity consider by themselves only the direction you can walk to or from or see the number's point from the zero point. Those directions are like the south and the north; the absolute value is like your way - you may walk not knowing the direction and still feeling the same tiredness:) JLincoln (discuss • contribs) 00:06, 22 August 2011 (UTC)
