Addition(+), Subtraction(-), Multiplication(x), and Division(/) are the fundamental arithmetic operations. Being able to accomplish these four operations on natural numbers and the derivative operations for percents, fractions, and decimals, with high efficiency and accuracy, is the core skills in the elementary mathematics, and is, therefore, indispensible for students’ success in their mathematics study in high schools and later on. While working on abundant practices and drills to get skillful in handling those four arithmetic operations, students build up their interest and confidence in math, and, at the same time, sharpen their brains for more challenges ahead in their personal and academic life. Studies have shown that mathematical skills and critical thinking skills are essential 21st century skills necessary for one to succeed in the increasing globalized world. It is, therefore, of high significance for the students to master these four operations at a young age.

Amongst these four operations, addition, the process of finding the sum of two or more numbers, is the foundation to the other three: subtraction is the inverse operation of addition; multiplication is a form of repeated addition of the same number; division is the inverse operation of multiplication.

Wreck Math (Addition), targeting the Addition operation, has three categories with varying focuses and difficulty levels: Addition within 10 Category, Addition within 20 Category, and Addition within 100 Category. Once the user selects the category after he/she launches the Wreck Math (Addition), he/she will start a fun and challenging journey for conquering the addition operation. The accuracy and response time of the user’s answers will determine how he/she is scoring in the current level and whether he/she is able to move on to the next level.

Wreck Math (Addition) is proud to boast the following characteristics and benefits:
•Concise and user-friendly interface
•Three categories to suit users’ varying abilities and desires in conquering mathematics
•Engaging and easy-to-play-with games build confidence and skills level by level
•Suitable for children (4+) to practice and improve their speed and accuracy in Addition
