**Introduction**** **

The word addition is derived from a Latin word â€œadditioâ€, which was used by an Italian mathematician, Leonardo Pisano Fibonacci and the sign of addition that is the “+” symbol first appeared in print in the year 1489 by Johann Widman. In modern mathematics, addition means a mathematical process that deals with putting things together. Whenever, you need to represent addition of certain things in a written form, use the “+” symbol. Addition is primarily a binary operation that deals with two objects simultaneously to give a result in another element of the same set.

**â€œTermsâ€ in addition**

â€œTermsâ€ in addition are the numbers or the objects that are added. They are also called the â€œaddendsâ€ or the â€œsummandsâ€. The first number or the object that you add is called the â€œaugend.â€ However, the term is no more in use during the present times due to the symmetry of addition.

**Units**** **

As far as units of addition are concerned, the first and foremost thing you should know is physical quantities of common units should be added. For instance, if you want to add 2 meters to 4 centimeters then it is better to convert either of the two quantities into a common unit. However, adding 8 meters to 4 square meters won’t yield any result as they are incomparable with each other.

**Features of addition**

- Addition is commutative, that means it will give the same result irrespective of the order. For instance, if you add 2 + 4, the result will be 6, however, if you change the order and add 4 + 2, the result will remain as 6. Therefore, addition provides the same result even if the orders are changed. This is also called â€œcommutative law of additionâ€. However, just as addition is a binary operation, it is not necessary for all other binary operation to follow the same law. In fact, subtraction and multiplication does not follow the commutative law.
- Addition is associative as well – you can add more than two numbers. For instance, you add 2 + 3 + 4. The only thing you need to do is to add any of the two numbers and then add the result of it to the remaining one. You will get the appropriate result.
- Zero has a special relation to addition as when zero is added to a number, the quantity never changes because zero is always the identity element for addition. Therefore, it is also called additive identity.

Addition is truly one of the simplest numerical tasks in mathematics. Addition like 1+1 are so simple that even kids can perform it with ease. To help them further, there are various visual representations of addition as well. The primary stage of addition includes single digit addition in the decimal system. As children grow up, they learn how to handle tougher additions. Moreover, addition is used to solve numerous problems in physical science as well.
