You can turn addition and subtraction into drawing methods. If your baby is interested in drawing, you can let your child learn addition and subtraction by drawing, so that you can intuitively see how addition and subtraction should be calculated. For example, draw two ducklings and then draw ten duck eggs. If four duck eggs were stolen by wolves, how many were there? When the baby can tell the answer accurately, give the baby appropriate encouragement.
