The process of finding the sum is a crucial operation in mathematics. It encompasses the addition of two or more numbers to obtain a cumulative total. As an illustration, when you add 2, 3, and 4 together, the result or sum is 9. This principle of summation is not limited to whole numbers alone, it can also be applied to fractions, decimals, and even complex numbers. Despite its simplicity, it is a pivotal component in a wide range of mathematical calculations.
