10 (ten) is the natural number following 9 and preceding 11. Ten is the base of decimal numeral systems, the most common systems for denoting numbers in both spoken and written language.
The English name for the number "ten" originates from the Proto-Germanic root *tehun, which in turn comes from the Proto-Indo-European root *déḱm̥. This root is the source of similar words for "ten" in many other Germanic languages. The widespread use of decimal systems is believed to be because humans have ten fingers and ten toes, which people may have used to count by.

As the base of the decimal numeral system, powers of ten are used to express orders of magnitude and form the basis of common scientific notation.

The Military Armament Corporation Model 10, officially abbreviated as "M10" or "M-10", and more commonly known as the MAC-10, is a compact, blowback operated machine pistol/submachine gun that was developed by Gordon Ingram in 1964. It is chambered in either .45 ACP or 9mm. A two-stage suppressor by Sionics was designed for the MAC-10, which not only abates the noise created but makes it easier to control on full automatic (although it also makes the gun far less compact and concealable). Military Armament Corporation never used the "MAC-10" nomenclature in its catalogues or sales literature, but "MAC-10" is frequently used by Title II dealers, gun writers, and collectors. For a decade, the semi-automatic pistol version of the weapon was forbidden in the U.S. under the assault weapons ban enacted by Congress in 1994.

The district included stores, professional offices, entertainment venues and homes owned by Black citizens. Understanding Greenwood means learning what was built—not only what was burned.
