She used to teach her daughter mathematics in a clever way. She easily taught her the number of daughters and taught her how much money she used for trading games. But when her mother taught her to multiply formulas, her daughter, Venetians, for the first time, showed dislike of learning, and despite her maneuvering her formulas into singing, she was still ineffective. How to do it? Mrs. Stena does not force her daughter to recite formulas, but rather to consult a very clever mathematical teaching professor.
