Preoperational children, typically aged 2 to 7 years according to Piaget's stages of cognitive development, do not yet have the ability to understand operations or the concept of reversibility, including understanding subtraction as the inverse of addition or division as the inverse of multiplication. This level of cognitive ability usually develops during the concrete operational stage, which starts around age 7.
