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 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.
