The kanji 数 is a phono-semantic compound (形声文字, keisei moji). The phonetic component is 娄 (rǒu/ロウ), which provided the sound. The semantic component, 米 (mǐ/ベイ, or "rice"), originally depicted grains of rice being counted. This association with rice likely stems from the importance of agriculture and the need to measure and keep track of harvests in ancient times. Over time, the rice radical was simplified and the meaning extended to the broader concept of numbers and counting.
