Addition Calculator

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
