"A simple and positive method of rapid addition, is outlined in this book. Its basic principle is sight reading of grouped figures, which is developed by familiarizing the student with every possible combination of three figures, so that each group may instantly be recognized and read as an aggregate without resorting to the addition of the separate figures composing it.."
