Addition

Addition is the process of combining two or more numbers to create a new value, and is generally considered the simplest form of mathematics. Despite its simplicity, the ability to perform basic addition is the foundation of most advanced mathematics, and simple addition, repeated millions of times per second, actually underlies much of the processing performed within the most advanced electronic computers on earth. Despite its elementary nature, the process of adding numbers together

remains one of the most useful mathematical operations available, as well as perhaps the most common type of calculation performed on a daily basis by most adults.
