The Sharp EL-S25 calculator asks the student a question (outlined below). The student then types in the answer to the question, and presses Enter / Equals. The calculator then marks the question. If the student was correct a new question appears, if the student was incorrect then the same question is repeated. Students who are struggling with a particular question can ask the calculator for the answer by leaving the answer blank and press equals. The calculator will then show the student what the answer should be. Students are able to learn from their mistakes and improve their results. At the end of every drill a total mark out of a possible 25, 50 or 100 is shown, along with their percentage.
