The Mock Turtle went on. “We had the best of educations . . . Reeling and Writhing, of course, to begin with, and then the different branches of Arithmetic—Ambition, Distraction, Uglification, and Derision.” “I never heard of Uglification,” Alice ventured to say. “What is it?” The Gryphon lifted up both its paws in surprise. “Never heard of uglifying!” it exclaimed. “You know what to beautify is, I suppose?” “Yes,” said Alice, doubtfully: it means—to—make—anything—prettier.” “Well, then,” the Gryphon went on, “if you don't know what to uglify is, you are a simpleton.” Here is a real working calculator that you can use to do your Ambition, Distration, Uglification, and Derision. I’ll bet that the Mock Turtle would have done a lot better in his Arithmetic if he had a calculator like this! (Can you figure out what the Mock Turtle really meant to say?)
