The three girls became so interested in their plans for the following day that Mathematics I. was almost forgotten, and when Marjorie remembered she was to show Jean the room it was fully five minutes after the hour. Stopping before a door marked "21" Marjorie said, "Here it is, and Miss Hooper is in charge. Oh, she's fierce; I pity you. I had Miss Baldwin, who's a regular cinch. I'll meet you here at the end of the hour if you like." As Jean entered the room Miss Hooper was just reading the class list and she heard "Miss Cabot" ring out distinctly in the stillness of the large room. "Here," said Jean, and she sank into the only vacant chair in the front row directly in front of the desk. Miss Hooper paused, looked up quickly from her class book and said sharply, "Five minutes late. A very bad beginning, Miss Cabot; remember hereafter, please, that this class meets promptly at nine o'clock." It was on Jean's tongue to say that she had lost her way, but something restrained her. Miss Hooper explained that the work of the year would be divided into three parts, algebra the first third of the year, geometry the second, and trigonometry the last. The class were to use Wells's College Algebra, which they could buy at the college book-store. The first lesson would be the problems on page 47. "And now, class, let us spend the rest of the hour reviewing a little. Miss Cabot, you may explain what is meant by the 'binomial theorem.'" Poor Jean tried to collect her scattered senses enough to answer the question. She remembered there was such a thing as this binomial theorem, but what it was she could not have told had her life depended upon it. After waiting as long as she dared she answered in a low voice, "I do not know." Miss Hooper looked annoyed and repeated the question to Miss Caldow, next on the list, who, to Jean's disgust, jumped on her feet and recited glibly and entirely to Miss Hooper's satisfaction. "Very well done, Miss Caldow. I see no reason why the entire class should not be perfectly familiar with the theorem. No one can expect to do any kind of work in advanced algebra unless she has a thorough foundation in the elementary work. Miss Cabot, you will please look up the binomial theorem and be prepared to recite it at the next meeting of the class." Jean thought the hour would never end, but when at last the class was excused she rushed from the room almost into the arms of Marjorie Remington who was waiting for her just outside the door. "Well, honey, how did Mathematics I. go?" "Terribly. I never want to see Miss Hooper again and I'll not take her old mathematics course another day. I don't know anything about algebra, and she pounced on me first one to explain the binomial theorem, and because I didn't know it she insulted me before the whole class."
