The Sumerians used hieroglyphics and cuneiform to write their texts, and developed the first codified legal system and military ranking system in the world. They invented the potter's wheel, the milled wheel and the first wheeled vehicles. They developed the mixed radix system of arithmetic with alternating bases of 10 and six. They were pioneers in inventing irrigation systems and growing crops.
The Sumerians were a highly ingenious people and many of the present-day articles that are so common and taken for granted today were invented by people who lived in Sumer. Examples of Sumerian resourcefulness can be seen even now in the form of articles such as several arithmetic and geometric concepts, armour, arrowheads, axes, bags, beer, bits, boots, braces, bronze, chisels, cuneiform (a form of writing on tablets, which is an ancient means of communication), daggers, glue, hammers, harnesses, harpoons, hoes, irrigation systems, knives, lancepoints, leather, the lunisolar calendar, nails, pins, quivers, rings, sandals, saws, scabbards, Sumerian boats, swords, waterskins and the wheel.
There were three types of Sumerian boats, namely ones made of animal skin and reeds (skinboats), clinker-built sailboats, made of hair and bitumen waterproofing and wooden-oared ships.
