My daughter is 3 yrs old and she is very active. I make to write alphabets n numbers 1 to 10 .recently I found that she is writing any number words and names even  in crores. If I give her addition , subtraction , division , multiply she just write the answer without even seeing the paper n question. Even algebra sums. Vocabulary in English, chemical formulas . I don't know how it is possible. Could anyone pls clarify . How to encourage her further and what should I do. P.s I never compelled her to write.
