Answer 3

from one of the articles linked to in Gocika's link

Shortening uno and ciento: Uno and numbers ending in -uno are shortened to un when they immediately precede a masculine noun. When standing alone (that is, being 100 exactly) ciento is shortened to cien before preceding a noun of either gender; the longer form is used within longer numbers (except when preceding mil).

Examples: un lápiz (1 pencil), una pluma (1 pen), cincuenta y un lápices (51 pencils), cincuenta y una plumas (51 pens), cien lápices (100 pencils), cien plumas (100 pens), ciento tres lápices (103 pencils), ciento tres plumas (103 pens), cien mil lápices (100,000 pencils), cien mil plumas (100,000 pens)
