Arithmetic Basics app for iPhone and iPad

This app is a simple tool for helping kids practice basic math, i.e. addition, subtraction, multiplication, and division. The quiz questions that the app asks are easily configurable: set the number of questions asked in each quiz, as well as the possible range of numbers that are used to make up the questions. Seven types of quizzes are possible: (1) Addition, (2) Subtraction, (3) Multiplication, (4) Division, (5) Addition and Subtraction, (6) Multiplication and Division, or (7) Everything (addition, subtraction, multiplication, and division questions).

Correct answers are indicated with a green check mark, while mistakes receive a red "X" along with the correct answer displayed also in red. Once all quiz questions are completed, any wrong answers can be re-tried.

After each quiz is completed, a letter grade is assigned based on the percentage of correct answers.
