Origin

This character most likely combines a picture of bamboo (the upper part) with elements representing counting or calculation below. Bamboo was historically used to make counting rods—thin sticks that were arranged in patterns to perform arithmetic before the abacus was invented. Over time, the character came to mean calculation, numbers, and probability more broadly. The shape has become simplified from its original pictographic form, but the connection to bamboo and the ancient counting methods it represents remains embedded in the character's meaning.
