Definition: Addition is one of the four basic arithmetic operations, which involves combining two or more numbers to find their total sum. It is denoted by the “+” symbol. In addition, the numbers being combined are called addends, and the resulting value is known as the sum.
Explanation: Addition is a fundamental concept in mathematics that involves combining numbers to find their total. It is often taught at an early age and is used extensively in everyday life.
To add numbers, you start by aligning the digits vertically, with the ones digit under the ones digit, the tens digit under the tens digit, and so on. You begin adding from the rightmost column (the ones column) and move to the left.
When adding two single-digit numbers, you simply add the two numbers together. For example, 3 + 4 = 7.
When adding larger numbers, such as two-digit numbers, you add the digits in the same place value column. If the sum of the digits in a column is less than 10, you write down the sum. However, if the sum is 10 or greater, you write down only the ones digit and carry the tens digit over to the next column.
For example, let’s add 45 and 27:
45
+ 27
——
72
In this example, the sum of the ones column (5 + 7) is 12, so we write down the 2 and carry the 1 to the next column. The sum of the tens column (4 + 2 + 1) is 7, so we write down the 7. The final sum is 72.
You can also add more than two numbers by adding them one at a time, starting with the leftmost number.
Additionally, addition has some important properties, such as commutativity (the order of the addends does not affect the sum) and associativity (the grouping of addends does not affect the sum).
Overall, addition is a fundamental mathematical operation that allows us to combine numbers and find their total sum. It is widely used in various mathematical operations, problem-solving, and real-life situations.
