10-key lesson 6: Operators / * - +

Your little finger covers the whole right column: -, + and Enter. It moves up and down while the other fingers stay on 4 5 6.

How each lesson works

Every lesson has three short exercises: the new keys on their own, a mix with keys you already know, and realistic numbers. Type each entry and press Enter. A wrong key turns red, and you can only move on with the right one. Pass with at least 92% accuracy. In the last exercise you earn up to three stars, depending on your speed in keystrokes per hour (KPH).
