Add two numbers quickly and accurately
Addition is one of the four fundamental arithmetic operations in mathematics. It is the process of combining two or more numbers (called addends) to produce a single number known as the sum or total. Addition is represented by the plus sign (+) and is the most basic operation taught in elementary mathematics. Whether you're working with whole numbers, decimals, fractions, or negative numbers, addition follows the same principle: combining quantities to find their total value.
To add two numbers, simply enter the first number (a) and the second number (b) into the calculator. The calculator will instantly compute the sum (a + b). Addition is commutative, meaning the order of the numbers doesn't matter: a + b = b + a. For example, 5 + 3 = 8 and 3 + 5 = 8. Addition is also associative, meaning when adding three or more numbers, the grouping doesn't matter: (a + b) + c = a + (b + c).
Our calculator automatically performs addition using the standard mathematical operation. It handles positive numbers, negative numbers, decimals, and very large numbers with high precision. Whether you're working on homework, solving math problems, calculating totals in real-world scenarios, or performing calculations in various fields, our addition calculator provides accurate, instant solutions.
If you enter 5 and 3, the result is 5 + 3 = 8. If you enter 12.5 and 7.3, the result is 12.5 + 7.3 = 19.8. If you enter -10 and 15, the result is -10 + 15 = 5. For any two numbers a and b, the calculator computes a + b accurately.
