The receiving person is required to be barefoot. The uncovered soles of the feet need to be placed in an exposed position. The beating is typically performed with an object in the type of a cane or switch. The strokes are usually
Of the form ("2k")("2l") = 4("kl") = 2("2kl"). Since "2kl" is also a natural number, the product is even. "Note:" In this case, both exhaustivity and exclusivity were needed. That is, it was not only necessary that every even number is of the form "2n" (exhaustivity), but also that every expression of the form "2n" is an even number (exclusivity). This will not be the case in every proof, but normally, at least exhaustivity is implied by the phrase of the form. Of the form In mathematics, the phrase "of the form" indicates that a mathematical object, or (more frequently) a collection of
