Addition is one of the basic mathematical operations, symbolized by the “+” sign. It consists in calculating the sum of two or more numbers. For example, in the addition 3 + 4, “3” and “4” are called the terms, and “7” is the sum.
Addition is an ancient operation, used by the most primitive civilizations to count and exchange goods. Numerical systems and methods of addition have evolved over time, becoming increasingly sophisticated with the invention of written numbers, the introduction of the zero and the development of mathematics.
Addition is fundamental to mental arithmetic. It is often the first mathematical operation taught to children, as it forms the basis for learning other mathematical concepts, such as subtraction and multiplication. Mastering addition is essential for developing logical thinking and solving everyday problems, such as calculating expenses or measuring time.
Let’s take a simple example: if you have three apples and add two more, you’ll get five apples in all, which can be represented as 3 + 2 = 5. This type of simple addition is a great way to start understanding the concept of addition and develop mental arithmetic skills.
