PROBLEM: Knife legislation -- In Spain there are stringent laws proscribing the carrying of armas blancas, or fighting knives, and prohibiting the manufacture, sale, possession or use of certain knives classified as prohibited weapons. Armas blancas and other sharp-bladed instruments or cutting tools may be freely purchased and owned provided they are not on the list of prohibited weapons, are not purchased or possessed by minors, are kept at home for the exclusive purpose of a collection, and are not transported on the public roads. It is against the law generally to carry, display or use any kind of knife in public, especially knives with pointed blades, unless one is on one's own property or is working or engaged in a legitimate sporting activity requiring the use of such a knife.

SOLUTION: is it legal to carry a knife in spain

PROBLEM: Standard deviation -- The standard deviation of a random variable, statistical population, data set, or probability distribution is the square root of its variance. It is algebraically simpler, though in practice less robust, than the average absolute deviation. A useful property of the standard deviation is that, unlike the variance, it is expressed in the same units as the data.

SOLUTION:
is variance the square root of standard deviation
