arithmetics trainer demo

by Limin P

Description

This program aims to train basic arithmetics, designed for children or whoever is bored during the quarantine time. It borrows ideas directly from the "khansole_academy" in assignment 2, but it gives 3 levels for the users to choose ---beginner, intermediate, and advanced. It also involves arithmetics of more steps (e.g. 3+5*6). Moreover, it has a timer function and gives the user feedback on whether their answer is correct and their overall performance.
