16 (number) 0 to 15 in each column. Sixteen is an even number and a square number. Sixteen is the fourth power of two. Sixteen is the only integer that equals "m" and "n", for some unequal integers "m" and "n" ("m" = 4, "n" = 2, or vice versa). It has this property because 2 = 2 × 2. It is also equal to 2 (see tetration). 16 is the base of the hexadecimal number system, which is used extensively in computer science. In Spanish and Portuguese, 16 is the first compound number (Spanish: "dieciséis", European Portuguese: "dezasseis", Brazilian Portuguese: "dezesseis");
Chinese given name take the names as divisible. In regions where fortune-telling is more popular, many parents may name their children on the advice of literomancers. The advice are often given based on the number of strokes of the names or the perceived elemental value of the characters in relation to the child's birth time and personal elemental value; rarely on the sound of the name as there is no system of fortune-telling based on character pronunciations. In jurisdictions where it is possible, people may also choose to change their legal given name, or their children's names, in order to improve their fortune.
