Byeoldosa: Arithmetic Practice

Practice Basic Arithmetic

Free · Designed for iPad

Byeoldosa is an arithmetic practice app for working through addition, subtraction, multiplication, and division step by step. • Levels are organised by difficulty, so you can start from the basics and move on to more advanced problems at your own pace. • Problems range from single-digit to three-digit numbers, with stages that change depending on whether carrying or borrowing is involved. • In vertical (column) calculation mode, you can follow each column one box at a time, much like writing out the sum on paper. • Every practice set is saved automatically, and your scores and time spent are shown in simple charts, so you can see how your speed and accuracy change as you keep practising. It’s a good fit for students who want to strengthen their arithmetic, for anyone who’d like a bit of mental exercise, or for those moments when you just feel like doing a few number problems. Whenever you feel like practising numbers, just open Byeoldosa.
