👉 Addition is a fundamental arithmetic operation that combines two or more numbers to find their total sum. In essence, it involves placing the digits of each number in corresponding positions (from right to left) and then adding the values in each column, carrying over any excess to the next higher place value. For example, adding 17 and 23 involves writing them as 17, 23 and then adding each column from right to left: (7+3) = 10, which becomes 1 carried over to the tens place, (1+7+carried 1) = 9, and (4+2+carried 1) = 7. Thus, the result is 40. This process continues until all digits have been added, providing a straightforward method to calculate the sum of numbers.
