This video on early childhood mathematics shows that children can learn linearity, integration and solving equations when allowed to count in icons less than ten, e.g. in 3s or 5s. To be added on-top, a unit must be changed, later called proportionality or linearity. Adding next-to as 8s is later called integration. And reversed addition is solving equations.
