We have named Shine Junior Aryabhatta after the great Indian mathematician and astronomer to encourage little champs to study mathematics and play with numbers. Mathematics is often a dreaded subject at school. SJAO is designed to help children become friends with the subject and master it with ease right in their formative years.
