Addition Calculator

The result is:

Addition is a basic arithmetic operation used in our daily life. An addition calculator makes your task simpler and faster, giving accurate results in significantly less time. It is a free online tool which helps in doing large calculations. While calculating our monthly expenses or grocery bills, addition is one of our most frequent operations.

What is Addition?

In mathematics, addition is the process of combining two or more values. It is the process of combining various values into one sum. The addition is denoted by the symbol "+".

The formula of Addition

Addend + Addend = Sum

In the addition procedure, the values are called addends and the resultant is known as the sum. Such as 2 + 1 = 3, where 2 and 1 are the addends, and 3 is the sum.

Example of Addition

1) Find the value.
82 + 65 = ?
To perform addition in the basic calculator. Enter all the given values using the addition operator (+), i.e.,
82 + 65 = 147

Find the value.
67 + 85 + 99 + 76 + 119 + 34 = ?
To perform addition in the basic calculator. Enter all the given values using the addition operator (+), i.e.,
67 + 85 + 99 + 76 + 119 + 34 = 480

How to use an Addition Calculator?

  1. Enter your first number (first addend) in the left column.
  2. Enter your second number (second addend) in the right column.
  3. Click on “Add” to get the result.


An Indian mathematician, Brahmagupta, first devised the modern methods for four fundamental operations, i.e., addition, subtraction, multiplication, and division.

There are four basic properties in addition.

  • Commutative Property

    When two numbers or integers are added, the sum remains the same even if we change the order of the numbers or integers.
    A + B = B + A

  • Associative Property

    On adding three numbers, the association of numbers in a different pattern does not change the result. That means the sum will be the same while adding three or more digits, even when the grouping of addends is altered.
    A + (B + C) = (A + B) + C

  • Distributive Property

    The distributive property of addition states that the sum of two numbers multiplied by a third number equals the sum of each number when multiplied with the third number.
    A × (B + C) = A × B + A × C

  • Additive Identity Property

    The additive identity property states that when a number is added to zero, it will give the same number. Hence, "zero" is called the identity element.
    A + 0 = A
    0 + A = A
