4 year old math kids doing calculus | algebra

Most of kids have ability to learn math at much earlier than most of us knew. We used numbers early in their daily activities. We also made math very simple for our kids that they enjoy learning math again and again as part of playful daily activities. With this rate, Steven will be able to solve core calculus problems with speed by 5 year old- or about a year from now.
I hope parents with young children can do the same - the earlier we use math at their activities, we will not only shift their math learning curves but they also condition to do math at their mental state at their natural progression without them develop fear at older age, As kids continue to depend on their common sens to solve problems, they don't need to know or to memorize most of the rules dim important by others from algebra, to calculus yet they will be solve random problems with speed and effectiveness at much younger age .
